    Introduction and Objectives: The intensive care unit (ICU) is an uncomfortable and stressful environment for patients. The use of adequate sedation and analgesia is important to reduce stress to patients. The aim of this study was to compare a relatively new sedative agent, dexmedetomidine to current sedative agent used, propofol in the provision of sedation and analgesia, their effects on haemodynamic and respiratory parameters and cost involved on post open heart surgery patients. Materials and Methods: A prospective, randomized single-blinded trial was conducted on post open heart surgery patients in the ICU of the Hospital Universiti Sains Malaysia (HUSM). Thirty two patients were randomized to dexmedetomidine or propofol groups. Analgesic requirement, haemodynamic and respiratory parameters, and extubation time were measured and compared. Mean rate of infusion to achieve adequate sedation were used to calculate the cost involved in the use of these two agents. Results: Patients sedated with dexmedetomidine required significantly lower dose of morphine compared to propofol [mean (sd): 12.80 (2.61) versus 15.86 (1.87) mg/kg/min, p=0.00]. Mean heart rate was also significantly lower in dexmedetomidine group compared to propofol group [mean (CI): 74.48 (70.38,78.59) versus 83.85 (79.61,88.09) per minutes, p=0.00]. However there were no significant differences in the other parameters between the two groups. Cost involved the use of dexmedetomidine was slightly higher compared to propofol (RM 9.57 versus RM8.94 per hour). Discussion and Conclusions: Dexmedetomidine is comparable to propofol in the provision of sedation, and its effect on haemodynamic and respiratory parameters. However it has added advantages in the provision of analgesia, and caused a significant reduction in heart rate. This is beneficial in these patients by reducing myocardial oxygen demand, and hence subsequent ischaemia and infarction. However, further larger studies are needed to evaluate the effect of dexmedetomidine on perioperative cardiac morbidity and mortality.

    Intrarticular Hyaluronic Acid was administered to 45 patients with various grades of osteoarthritis in the knee. Following 3 fortnightly injections, these patients were reviewed at 6 weeks and 3 months with regard to their knee pain. We found the most patients (84.4%) has decreased knee pain following these injections. Patients who had severe grade osteoarthritis based on knee radiographs before the injections were less likely to have pain reduction compared to those with milder grade osteoarthritis. Only 4 (8.9%) patients showed no improvement and were subsequently considered for surgery. Many patients did not require any further treatment (24.4%) and the remaining were given analgesia (64.4%) to aid in their pain. One patient required another course of this injection. there were no complications recorded in this study. We concluded that Intrarticular Hyaluronic acid is an easy and safe method to treat osteoarthritis. The short-term outcome with regard to knee pain is good in patients with milder grades of osteoarthritis.

    Congenital partial aplasia of the atlas with a posterior arch remnant is rare. It may be found as an incidental radiological finding or patients can present with neurological signs and symptoms after head or neck trauma. A 36-year-old female presented with a 3-day history of right sided neck pain radiating down the right arm. Radiographs of the cervical spine showed a radiolucent area in the region of the posterior arch of the atlas. Computed tomography subsequently revealed partial absence of the posterior arch of the atlas with a defect at the anterior ring. Her clinical condition subsequently improved with rest, analgesia and physiotherapy. This case report illustrates a situation where congenital defect of the posterior arch of the atlas was revealed in a patient with neck pain. Awareness of the existence of this condition will help clinicians avoid misdiagnosis and excessive investigations.

    Acute appendicitis is one of the most common differential diagnoses for acute abdominal pain made by emergency doctors. Suspected cases require surgical referral for observation or definitive intervention to prevent complications. A high index of suspicion and good clinical skills with the aid of scoring systems allows early decision making, which includes optimal pain control. The objective of this study was to identify the pain score and is relationship to the cut-off points of the Alvarado scoring system so that justifies early surgical referral or discharge for suspected acute appendicitis from the Emergency Department of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). This was a cross sectional study of acute abdominal pain from June 2007 to September 2008. All patients who fulfilled the criteria and consented to the study were assessed for Alvarado score, verbal numerical pain score (VNRS) and their subsequent management. Patients with an Alvarado score of ≥7 were likely to have acute appendicitis (80.1% sensitivity and 52.63% specificity) and those with the score of ≤3 were unlikely to have acute appendicitis. The median pain score was 7.00 (IQR: 5.00-8.50) but 72.5% did not receive any analgesia. There was no direct relationship between the pain score with Alvarado score. Oligoanalgesia in patients with acute appendicitis still exist in Emergency Department of UKMMC.

    Introduction: Total knee arthroplasty (TKA) is associated with intense postoperative pain for which effective analgesia is essential to facilitate early postoperative recovery. Adductor canal block (ACB) and local infiltration analgesia (LIA) have become increasingly involved in postoperative pain management after TKA. We aimed to compare their efficacy and outcomes in patients undergoing TKA. Materials and Methods: Sixty patients undergoing unilateral TKA were randomized to receive either postoperative single-injection ACB (Group A) or LIA (Group L) during the operation. All patients received spinal anaesthesia. Primary outcome was total morphine consumption over postoperative 24 hours. Visual analog pain scale, time to first and total dosage of rescue analgesia, performance-based evaluations [timed-up and go (TUG) test, quadriceps strength], side-effects, length of hospital stay and patient satisfaction were measured. Results: Fifty-seven patients were available for analysis. Median total morphine consumption over 24 and 48 postoperative hours of Group A were significantly less than Group L (6/10 mg vs 13/25 mg, p, 0.008 and 0.001, respectively). Similarly, Group A had significantly lower VAS at postoperative 6, 12 and 18 hours, VAS at ambulation on postoperative (POD) 1-3, better TUG tests on POD 2 and during POD 3 than those of Group L. However, quadriceps strength and patient satisfaction were not different between both groups. Conclusion: Patients undergoing TKA with single-injection ACB required less postoperative opioids than those with LIA. Furthermore, multimodal analgesia using ACB provided better postoperative analgesia, as well as performance-based activities, than those with LIA.

    AIM: The diagnosis of tongue-tie (or ankyloglossia) has increased more than 10-fold in some countries. Whether this is a global phenomenon or related to cultural and professional differences is uncertain.

    METHODS: An online survey in English, Japanese, Chinese and Spanish was disseminated between May and November 2016 via 27 international professional bodies to >30 clinical professions chosen a priori to represent occupations involved in the management of neonatal ankyloglossia.

    RESULTS: A total of 1721 responses came from nursing (51%), medical (40%), dental (6%) and allied health (4%) clinicians. Nurses (40%) and allied health (34%) professionals were more likely than doctors (8%) to consider ankyloglossia as important for lactation problems, as were western (83%) compared to Asian (52%) clinicians. Referrals to clinicians for ankyloglossia management originated mainly from parents (38%). Interprofessional referrals were not clearly defined. Frenectomies were most likely to be performed by surgeons (65%) and dentists (35%), who were also less likely to be involved in lactation support. Clinicians performing frenectomies were more likely to consider analgesia as important compared to those not performing frenectomies.

    CONCLUSION: The diagnosis and treatment of ankyloglossia vary considerably around the world and between professions. Efforts to standardise management are required.

    The present study aims to investigate the analgesic activity of the methanol extract of the galls of Quercus infectoria in rats using hot plate and tail-flick methods. The extract was administered intraperitoneally at a dose of 20 mg/kg while morphine sulfate and sodium salicylate (10 mg/kg) served as standards. The methanol extract exhibited significant analgesic activity in the tail-flick model (P < 0.05) by increasing the reaction time of the rats to 8.0 sec at 30 min after treatment in comparison to control (4.4 sec). Morphine sulfate produced a reaction time of 11.9 sec in the same test. At the peak of activity (30 min), the extract produced maximum possible analgesia (MPA) of 34.2%, whilst morphine sulfate achieved a peak MPA of 70.9%. No analgesic effects have been observed using sodium salicylate in the tail-flick model. In the same model, the extract and sodium salicylate demonstrated comparable reaction times. Tail-flick is a better method to evaluate analgesic activity as no significant results were observed for all treatments using hot plate with the exception of morphine sulfate, which showed significant results only at 45 and 60 min after treatment. In conclusion, the methanol extract of the galls of Quercus infectoria displayed analgesic activity.

    BACKGROUND: This was a double-blinded, prospective randomized controlled trial to compare the postoperative analgesia, side effects profile and overall satisfaction in patients who received intrathecal fentanyl with or without morphine for elective Caesarean.
    METHODS: Sixty ASA I and II parturients were randomized into two groups. Group I received intrathecal fentanyl with 0.1 mg morphine and Group II received intrathecal fentanyl only. Postoperatively, all patients were provided with oral analgesics. The degree of post-operative pain score was assessed by verbal pain score. The incidence of side effects was assessed every 4 hours for 24 hours, which included incidence of nausea, vomiting, pruritus, sedation and evidence of respiratory depression. Patient's overall satisfaction was also recorded.
    RESULTS: The verbal pain score was significantly lower in morphine group up to 20 hours postoperative period. The incidence of pruritus, nausea and vomiting were statistically significant up to 12 hours postoperative. There was no incidence of severe side effects in all the patients. There was significant difference between the morphine and no morphine group in terms of overall patient satisfaction.
    CONCLUSION: There was significant difference in terms of lower pain score, higher incidence of side effects with better patients' overall satisfaction in morphine group.

    This was a prospective randomised, controlled, single-blind study done to determine the effect of intrathecal morphine 0.1 mg as compared with intrathecal fentanyl 25 microg in terms of analgesia and duration for postoperative pain relief after Caesarean section. Sixty ASA I or II parturients were randomised into two groups. Group 1 (n=33) received 1.8 ml of 0.5% hyperbaric bupivacaine combined with 0.1 mg morphine while Group 2 (n=27) received 1.8 ml of 0.5% hyperbaric bupivacaine combined with 25 microg fentanyl for spinal anaesthesia. Postoperatively, all patients were provided with patient controlled analgesia (PCA) morphine. Pain was assessed using visual analogue score (VAS) at 6, 12, 18 and 24 hours. Time to first demand of PCA morphine, cumulative PCA morphine requirement and opioid side effects were documented. The VAS for pain and the cumulative PCA morphine requirement were both significantly lower in Group 1 (p < 0.05) during the 24 hours study period. The time to first demand was also significantly longer in Group 1 (p < 0.05). Overall, there were no significant difference between the two groups in side effects, except for a high incidence of nausea and vomiting requiring treatment in Group B in the first six hours. In conclusion the addition of 0.1 mg morphine for spinal anaesthesia provided superior and longer postoperative analgesia after Caesarean section.

    The success of major surgery depends partly on providing effective post-operative pain relief, which can be commonly achieved by morphine administration via patient- controlled analgesic (PCA) system. Alternatively, tramadol which is a weak opioid analgesic, can be used for post operative pain relief. The purpose of this study was to evaluate the effectiveness of intravenous PCA tramadol in comparison with PCA morphine in term of analgesic properties, sedation and side effects. A randomized, double-blinded study was conducted on 160 ASA I and II patients who underwent major operations. Eighty of them received a loading dose of intravenous morphine 0.1 mg/kg followed by PCA morphine bolus of 1 mg (1 mg/ml) as required, while the other 80 patients received a loading dose of 2.5 mg/kg of intravenous tramadol followed by PCA infusion of 10 mg (10 mg/ml) as required. Patients were monitored for pain, sedation and side effects as well as respiratory rate, nausea, vomiting, pruritus, blood pressure and pulse rate. Patients were evaluated 30 minutes, 4 hours, 24 hours and 48 hours post operation. There were no differences in the demographic data between the two groups (p > 0.05). The overall mean pain score in tramadol group was 0.70 +/- 0.60 as compared to 0.75 +/- 0.67 for morphine group. The mean pain score for tramadol and morphine groups at 30 minutes, 4 hours, 24 hours and 48 hours post operation were 1.32 +/- 0.79, 104 +/- 0.79, 0.35 +/- 0.48, 0.09 +/- 0.33 and 1.35 +/- 0.99, 1.14 +/- 0.81, 0.40 +/- 0.54, 0.10 +/- 0.34 respectively. The overall mean sedation score in tramadol and morphine group was 0.39 +/- 0.44 as compared to 0.35 +/- 0.43 for morphine group. The mean sedation score for tramadol and morphine group at 30 minutes, 4 hours, 24 hours and 48 hours post operation were 0.90 +/- 0.74, 0.56 +/- 0.59, 0.075 +/- 0.27, 0.025 +/- 0.16 and 0.84 +/- 0.70, 0.46 +/- 0.64, 0.08 +/- 0.27, 0.01 +/- 0.11 respectively. There was no significant difference in the overall mean pain and sedation score between the two groups as well as for each duration assessed (p > 0.05). There were also no significant differences between the two groups with regard to the blood pressure and heart rate. The incidence of nausea, vomiting and pruritus were the same in the two groups. This study indicates that PCA tramadol is as equally effective as PCA morphine control following major surgery. The incidences of sedation, nausea or pruritus were the same in the two groups.

    BACKGROUND: We assessed associations between intraoperative neuraxial block and postoperative epidural analgesia, and a composite primary outcome of death or non-fatal myocardial infarction, at 30 days post-randomization in POISE-2 Trial subjects.

    METHODS: 10 010 high-risk noncardiac surgical patients were randomized aspirin or placebo and clonidine or placebo. Neuraxial block was defined as intraoperative spinal anaesthesia, or thoracic or lumbar epidural anaesthesia. Postoperative epidural analgesia was defined as postoperative epidural local anaesthetic and/or opioid administration. We used logistic regression with weighting using estimated propensity scores.

    RESULTS: Neuraxial block was not associated with the primary outcome [7.5% vs 6.5%; odds ratio (OR), 0.89; 95% CI (confidence interval), 0.73-1.08; P=0.24], death (1.0% vs 1.4%; OR, 0.84; 95% CI, 0.53-1.35; P=0.48), myocardial infarction (6.9% vs 5.5%; OR, 0.91; 95% CI, 0.74-1.12; P=0.36) or stroke (0.3% vs 0.4%; OR, 1.05; 95% CI, 0.44-2.49; P=0.91). Neuraxial block was associated with less clinically important hypotension (39% vs 46%; OR, 0.90; 95% CI, 0.81-1.00; P=0.04). Postoperative epidural analgesia was not associated with the primary outcome (11.8% vs 6.2%; OR, 1.48; 95% CI, 0.89-2.48; P=0.13), death (1.3% vs 0.8%; OR, 0.84; 95% CI, 0.35-1.99; P=0.68], myocardial infarction (11.0% vs 5.7%; OR, 1.53; 95% CI, 0.90-2.61; P=0.11], stroke (0.4% vs 0.4%; OR, 0.65; 95% CI, 0.18-2.32; P=0.50] or clinically important hypotension (63% vs 36%; OR, 1.40; 95% CI, 0.95-2.09; P=0.09).

    CONCLUSIONS: Neuraxial block and postoperative epidural analgesia were not associated with adverse cardiovascular outcomes among POISE-2 subjects.

    The Multicenter Australian Study of Epidural Anesthesia and Analgesia in Major Surgery (The MASTER Trial) was designed to evaluate the possible benefit of epidural block in improving outcome in high-risk patients. The trial began in 1995 and is scheduled to reach the planned sample size of 900 during 2001. This paper describes the trial design and presents data comparing 455 patients randomized in 21 institutions in Australia, Hong Kong, and Malaysia, with 237 patients from the same hospitals who were eligible but not randomized. Nine categories of high-risk patients were defined as entry criteria for the trial. Protocols for ethical review, informed consent, randomization, clinical anesthesia and analgesia, and perioperative management were determined following extensive consultation with anesthesiologists throughout Australia. Clinical and research information was collected in participating hospitals by research staff who may not have been blind to allocation. Decisions about the presence or absence of endpoints were made primarily by a computer algorithm, supplemented by blinded clinical experts. Without unblinding the trial, comparison of eligibility criteria and incidence of endpoints between randomized and nonrandomized patients showed only small differences. We conclude that there is no strong evidence of important demographic or clinical differences between randomized and nonrandomized patients eligible for the MASTER Trial. Thus, the trial results are likely to be broadly generalizable.

    BACKGROUND: Stress-induced analgesia (SIA) is an evolutionarily conserved phenomenon during stress. Neuropeptide S (NPS), orexins, substance P, glutamate and endocannabinoids are known to be involved in stress and/or SIA, however their causal links remain unclear. Here, we reveal an unprecedented sequential cascade involving these mediators in the lateral hypothalamus (LH) and ventrolateral periaqueductal gray (vlPAG) using a restraint stress-induced SIA model.

    METHODS: Male C57BL/6 mice of 8-12 week-old were subjected to intra-cerebroventricular (i.c.v.) and/or intra-vlPAG (i.pag.) microinjection of NPS, orexin-A or substance P alone or in combination with selective antagonists of NPS receptors (NPSRs), OX1 receptors (OX1Rs), NK1 receptors (NK1Rs), mGlu5 receptors (mGlu5Rs) and CB1 receptors (CB1Rs), respectively. Antinociceptive effects of these mediators were evaluated via the hot-plate test. SIA in mice was induced by a 30-min restraint stress. NPS levels in the LH and substance P levels in vlPAG homogenates were compared in restrained and unrestrained mice.

    RESULTS: NPS (i.c.v., but not i.pag.) induced antinociception. This effect was prevented by i.c.v. blockade of NPSRs. Substance P (i.pag.) and orexin-A (i.pag.) also induced antinociception. Substance P (i.pag.)-induced antinociception was prevented by i.pag. Blockade of NK1Rs, mGlu5Rs or CB1Rs. Orexin-A (i.pag.)-induced antinociception has been shown previously to be prevented by i.pag. blockade of OX1Rs or CB1Rs, and here was prevented by NK1R or mGlu5R antagonist (i.pag.). NPS (i.c.v.)-induced antinociception was prevented by i.pag. blockade of OX1Rs, NK1Rs, mGlu5Rs or CB1Rs. SIA has been previously shown to be prevented by i.pag. blockade of OX1Rs or CB1Rs. Here, we found that SIA was also prevented by i.c.v. blockade of NPSRs or i.pag. blockade of NK1Rs or mGlu5Rs. Restrained mice had higher levels of NPS in the LH and substance P in the vlPAG than unrestrained mice.

    CONCLUSIONS: These results suggest that, during stress, NPS is released and activates LH orexin neurons via NPSRs, releasing orexins in the vlPAG. Orexins then activate OX1Rs on substance P-containing neurons in the vlPAG to release substance P that subsequently. Activates NK1Rs on glutamatergic neurons to release glutamate. Glutamate then activates perisynaptic mGlu5Rs to initiate the endocannabinoid retrograde inhibition of GABAergic transmission in the vlPAG, leading to analgesia.

    OBJECTIVE: Pain severity and opioid requirements in the postoperative period show substantial and clinically significant inter-patient variation due mainly to factors such as age, surgery type, and duration. Genetic factors have not been adequately assessed except for the neuronal OPRM1 rs1799971 and COMT rs4680, whereas the contribution of innate immune signaling pathway genetics has seldom been investigated.

    SETTING: Hospital surgical ward.

    SUBJECTS: Women (107 Indian, 184 Malay, and 750 Han Chinese) undergoing total hysterectomy surgery.

    METHODS: Morphine consumption, preoperative pain, and postoperative pain were evaluated in relation to genetic variability comprising 19 single-nucleotide polymorphisms (SNPs) in 14 genes involved in glial activation, inflammatory signaling, and neuronal regulation, plus OPRM1 (1 SNP) and COMT (3 SNPs).

    RESULTS: Pre- and postoperative pain and age were associated with increased and decreased morphine consumption, respectively. In Chinese patients, only 8% of the variability in consumption could be explained by these nongenetic and genetic (BDNF, IL1B, IL6R, CRP, OPRM1, COMT, MYD88) factors. However, in Indian patients, 41% of morphine consumption variability could be explained by age (explaining <3%) and variants in OPRM1 rs1799971, CRP rs2794521, TLR4 rs4986790, IL2 rs2069762, COMT rs4818, TGFB1 rs1800469, and IL6R rs8192284 without controlling for postoperative pain.

    CONCLUSIONS: This is the highest known value reported for genetic contributions (38%) to morphine use in the acute postoperative pain setting. Our findings highlight the need to incorporate both genetic and nongenetic factors and consider ethnicity-dependent and nonadditive genotypic models in the assessment of factors that contribute to variability in opioid use.

    INTRODUCTION: Craniotomy tumour is brain surgery that can induce a stress response. The stress response can be measured using haemodynamic parameters and plasma cortisol concentration. The stress response that occurs can affect an increase in sympathetic response, such as blood pressure and heart rate, which can lead to an increase in intracranial pressure. Scalp block can reduce the stress response to surgery and post-operative craniotomy tumour pain. The local anaesthetic drug bupivacaine 0.25% is effective in reducing post-operative pain and stress in the form of reducing plasma cortisol levels. The adjuvant addition of clonidine 2 μg/kg or dexamethasone may be beneficial.

    MATERIALS AND METHODS: A randomised control clinical trial was conducted at the Central Surgery Installation and Hasan Sadikin General Hospital Bandung and Dr. Mohammad Husein Hospital Palembang from December 2022 to June 2023. A total of 40 participants were divided into two groups using block randomisation. Group I receives bupivacaine 0.25% and clonidine 2 μg/kg, and group II receives bupivacaine 0.25% and dexamethasone 8 mg. The plasma cortisol levels of the patient will be assessed at (T0, T1 and T2). All the patient were intubated under general anesthaesia and received the drug for scalp block based on the group being randomised. Haemodynamic monitoring was carried out.

    RESULTS: There was a significant difference in administering bupivacaine 0.25% and clonidine 2μg/kg compared to administering bupivacaine 0.25% and dexamethasone 8 mg/kg as analgesia for scalp block in tumour craniotomy patients on cortisol levels at 12 hours post-operatively (T1) (p=0.048) and 24 hours post-surgery (T2) (p=0.027), while post-intubation cortisol levels (T0) found no significant difference (p=0.756). There is a significant difference in Numeric Rating Scale (NRS) at post-intubation (T0) (p=0.003), 12 hours post-operatively (T1) (p=0.002) and 24 hours post-surgery (T2) (p=0.004), There were no postprocedure scalp block side effects in both groups.

    CONCLUSION: The study found that scalp block with 0.25% bupivacaine and 2μg/kg clonidine is more effective in reducing NRS scores and cortisol levels compared bupivacaine 0.25% and dexamethasone 8mg in tumour craniotomy patients.

    WHAT IS KNOWN AND OBJECTIVE: Interindividual variability in drug responses may be attributable to genetically determined alteration in enzyme activity. In this study, we investigated the association between cytochrome P450 3A4 (CYP3A4) genetic polymorphisms and post-operative fentanyl requirements.

    METHODS: Patients (n = 94) scheduled for gynaecological laparotomy received i.v. fentanyl infusion (3 μg/kg/h) after induction of general anaesthesia. Post-operative fentanyl requirements were quantified by using a patient-controlled analgesia and the number of i.v. fentanyl rescue analgesia required were recorded. Pain control was assessed using visual analogue scores (VAS) and fentanyl's adverse effects were documented. CYP3A4*4, CYP3A4*5 and CYP3A4*18 alleles of cytochrome P450 3A4 were identified by polymerase chain reaction-restriction fragment length polymorphism. Differences in fentanyl requirements, VAS scores and adverse effects among the various genotypes were compared.

    RESULTS AND DISCUSSION: No CYP3A4*4 and CYP3A4*5 alleles were detected. Eighty-nine patients (94·7%) were wild-type, five (5·3%) were heterozygous and none was homozygous. No significant difference was demonstrated between the genotype groups in terms of fentanyl consumption, pain control and adverse effects.

    WHAT IS NEW AND CONCLUSION: CYP3A4*4 and CYP3A4*5 are rare in the Malaysian Malay population. Genetic polymorphism of CYP3A4*18 may not play an important role in influencing postoperative fentanyl requirements.

    Adequate pain relief is a requisite for a successful closed manipulative reduction (CMR) of fractures and dislocations. This prospective study was undertaken to assess the mode and adequacy of pain relief given to patients undergoing such procedures at Seremban Hospital from the 1st April to the 31st May 2001. All patients with fractures and dislocations scheduled to undergo CMR were included in this study. The type of sedative agents and analgesia administered were recorded. Demographic data and the type of fracture or dislocation of the selected patients were documented. A visual analogue scale (VAS) for pain perception was given to both to the patients and the medical personnel who performed the procedure. All data were collected manually before entered into computerized database for analysis. Of 72 patients included in this study, 47% were Malay, 26% Indian, 21% Chinese and 6% others. There was male predominance and the patients' age ranged between 9 to 79 years (average 27.4 years). Upper limb injuries (79%) were mainly fractures of the radius and ulna (29%) and isolated fracture radius (21%). For the lower limb injuries (21%), combined tibia and fibula fractures constituted 10% of the total cases followed by isolated tibia fractures (10%) and hip dislocation (1%). The most common pain relieving agents given during the CMR were intravenous pethidine alone (43%) followed by combination of intravenous pethidine and valium (36%), intramuscular pethidine (17%) and intramuscular tramal (4%). The Visual Analogue Score (VAS) for pain perception revealed that 61% of the patients had moderate pain while 21% had severe pain during the course of the procedures. Suboptimal pain relief administered during CMR should prompt positive actions to ensure that the patient is not subjected to undue pain just for the sake of an acceptable fracture reduction.
