METHODS: This prospective, double-blind, randomized study enrolled 60 female patients scheduled for unilateral mastectomy and axillary clearance. The patients received either a superficial serratus plane block or deep serratus plane block. Dermatomal spread was recorded 30 minutes after block administration. Postoperatively, pain visual analog scale (VAS) scores were documented at recovery (time 0), at 30 minutes; and in the ward hourly for 4 hours, and 4-hourly until 24 hours postoperatively. The time to first analgesic rescue and cumulative morphine consumption using patient-controlled analgesia morphine (PCAM) were recorded.
RESULTS: The results showed lower VAS scores at rest (at 1, 2, 3, and 4 hours postoperatively), and during movement (at 1, 2, 3, 4, 8, and 24 hours postoperatively) in the superficial serratus plane block group, P < .005. Similarly, cumulative morphine usage was lower in the superficial serratus plane group, P < .005. The time to the first rescue analgesic was also significantly longer in the superficial group, P < .001. More patients in the superficial serratus plane group achieved greater dermatomal spread at T2 and T7 than those in the deep group.
CONCLUSIONS: Superficial serratus plane block provides better analgesic efficacy than deep serratus plane block in mastectomy and axillary clearance.
MATERIAL AND METHODS: A single centre, cohort study evaluating 335 women who have undergone unilateral mastectomy between January 2017 and March 2020 in Malaysia. Regional anaesthesia were given pre-operatively via ultrasound guided pectoral and intercostal nerves block (PECSII).
RESULTS: Utilization of regional anaesthesia increased from 11% in 2017 to 43% in 2020. Types and duration of surgeries were comparable. Opiod consumption was 3 mg lower in those who had PECS2 block ((27 [24-30] mg), in comparison with those who received general anaesthesia only (30 [26-34] mg), p pain score (2 [1-3]; 2 [1-3], p=0.719) and post-operative nausea and vomiting (PONV) (32.6-32.5%, p = 0.996) were similar.
CONCLUSION: This study highlights the importance of PECS2 block as a component of ERAS protocol for mastectomy in an Asian hospital. This study also inferred that patients may be safely discharged within 24 h of surgery and therefore, same day surgery may be feasible in selected group of patients undergoing mastectomy and this could imply overall cost benefits.
MATERIALS AND METHODS: This double-blinded RCT enrolled 110 patients who underwent laparoscopic sleeve gastrectomy at Hospital Canselor Tuanku Muhriz UKM from November 2020 to May 2021. Any patients with previous abdominal surgery, chronic kidney disease, or liver disease were excluded. The patients were randomised into two groups: (i) the IPLA group which received ropivacaine intraperitoneal instillation at the dissected left crus and (ii) the placebo group (sterile water instillation). Perioperative analgesia was standardised. The first 24-h postoperative pain was assessed using a VAS. The respiratory effort was assessed using incentive spirometry simultaneously.
RESULTS: Total of 110 patients were recruited. The VAS score was lower with an enhanced recovery of respiratory effort in the local anaesthetic group compared to the placebo group (P < 0.05) within the first 24 h postoperatively. In addition, the placebo group required additional postoperative analgesia (P < 0.05). No side effects were reported with the use of intraperitoneal instillation of ropivacaine.
CONCLUSION: The use of intraperitoneal instillation of ropivacaine in laparoscopic sleeve gastrectomy is recommended as it is safe, effectively reduces acute postoperative pain, and enhances the recovery of respiratory effort postoperatively.
OBJECTIVES: The aim of this review was to investigate the effect of intravenous magnesium on the consumption of postoperative morphine in the first 24 h in adults undergoing noncardiac surgery.
DESIGN: Systematic review and meta-analysis with trial sequential analysis.
DATA SOURCES: MEDLINE, EMBASE, CENTRAL from their inception until January 2019.
ELIGIBILITY CRITERIA: All randomised clinical trials comparing intravenous magnesium versus placebo in noncardiac surgery were systematically searched in the databases. Observational studies, case reports, case series and nonsystematic reviews were excluded.
RESULTS: Fifty-one trials (n=3311) were included for quantitative meta-analysis. In comparison with placebo, postoperative morphine consumption at 24-h was significantly reduced in the magnesium group, with a mean difference [95% confidence interval (CI)] of -5.6 mg (-7.54 to -3.66, P pain scores in the first 24 h (mean difference, 95% CI) -0.30 (-0.69 to 0.09, P = 0.13, I = 91%, level of evidence low), bradycardia (odds ratio, 95% CI) 1.13 (0.43 to 2.98, P = 0.80, I = 35%, level of evidence very low) and postoperative nausea and vomiting (odds ratio, 95% CI) 0.90 (0.67 to 1.22, P = 0.49, I = 25%, level of evidence moderate).
CONCLUSION: The current meta-analysis demonstrates that the use of intravenous magnesium as part of multimodal analgesia may reduce morphine consumption in the first 24 h after surgery and delay the time to the first request for analgesia in patients undergoing noncardiac surgery. However, the included studies were of low-quality with substantial heterogeneity.
TRIAL REGISTRATION: CRD42018086846.
METHODOLOGY: The study was designed as a double-blind, randomized controlled trial involving 94 patients who underwent open thyroidectomy or parathyroidectomy in Hospital Pulau Pinang, Malaysia, from November 2015 to November 2016. The study compared the efficacy of pre-incision wound infiltration of diclofenac (n = 47) versus bupivacaine (n = 47) in post-operative pain relief. Wound infiltration is given prior to skin incision. Mean pain score at designated time interval within the 24-h post-operative period, time to first analgesia, total analgesic usage and total analgesic cost were assessed.
RESULTS: Ninety-four patients were recruited with no dropouts. Mean age was 49.3 (SD = 14.2) with majority being female (74.5%). Ethnic distribution recorded 42.6% Chinese, 38.3% Malay, followed by 19.1% Indian. Mean duration of surgery was 123.8 min (SD = 56.5), and mean length of hospital stay was 4.7 days (SD = 1.8). The characteristics of patient in both groups were generally comparable except that there were more cases of total thyroidectomy in the diclofenac group (n = 31) as compared to the bupivacaine group (n = 16). Mean pain score peaked at immediate post-operative period (post-operative 0.5 h) with a score of 3.5 out of 10 and the level decreased steadily over the next 20 h starting from 4 h post-operatively. Pre-incision wound infiltration using diclofenac had better pain control as compared to bupivacaine at all time interval assessed. In the resting state, the mean post-operative pain score difference was statistically significant at 2 h [2.1 (SD = 1.5) vs. 2.8 (SD = 1.8), p = 0.04]. During neck movement, the dynamic pain score difference was statistically significant at post-operative 1 h [2.7 (SD = 1.9) vs. 3.7 (SD = 2.1), p = 0.02]; 2 h [2.7 (SD = 1.6) vs. 3.7 (SD = 2.0), p = 0.01]; 4 h [2.2 (SD = 1.5) vs. 2.9 (SD = 1.7), p = 0.04], 6 h [1.9 (SD = 1.4) vs. 2.5 (SD = 1.6), p = 0.04] and 12 h [1.5 (SD = 1.5) vs. 2.2 (SD = 1.4), p = 0.03]. Mean dose of tramadol used as rescue analgesia in 24 h duration was lower in the diclofenac group as compared to bupivacaine group [13.8 mg (SD = 24.9) vs. 36.2 mg (SD = 45.1), p = 0.01]. The total cost of analgesia used was significantly cheaper in diclofenac group as compared to bupivacaine group [RM 3.47 (SD = 1.51) vs. RM 13.43 (SD = 1.68), p pain relief compared to bupivacaine for patient who had underwent open thyroidectomy or parathyroidectomy. Diclofenac is cheap and easily available in the limited resource setting. This approach offers a superior alternative for post-operative pain relief as compared to bupivacaine.
METHODOLOGY: The trial is reported according to the Preferred Reporting Items for RAndomized Trials in Endodontics (PRIRATE) 2020 guidelines. The protocol was registered at the clinical trial registry (India) (CTRI/2019/06/019818). In total, 160 patients, assigned to four groups, received orally either 20 mg piroxicam, 20 mg prednisolone, 4 mg dexamethasone or a placebo 60 min before root canal treatment. Patients recorded their postoperative pain intensity at 6, 12, 24, 48 and 72 h using a 10-cm visual analogue scale. Intergroup comparison was performed using Kruskal-Wallis tests with post hoc analysis using Dunns test. Incidence of pain was analysed using chi-square tests. A P value pain, with incidence of pain as the dependent variable and intervention groups, gender, age and type of tooth as independent variables.
RESULTS: In total, 156 patients were analysed in the trial, since four patients dropped out during follow-up. All drugs were associated with a significantly lower incidence of postoperative pain compared to the placebo at 6 h (P = 0.009), 12 h (P = 0.003) and 24 h (P = 0.008). Mean intensity of pain was significantly more intense at 6, 12 and 24 h with the use of placebo in comparison to the other three intervention groups (P pain was not significantly different between the premedications used (P > 0.05). One patient in the piroxicam group reported gastritis, whereas no adverse effects were recorded in other groups.
CONCLUSION: Preoperative oral administration of a single dose of 4 mg dexamethasone, 20 mg piroxicam or 20 mg prednisolone reduced the incidence and severity of postoperative pain following single-visit root canal treatment compared to a placebo in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis up to 24 h. The odds of postoperative pain at 24 h for patients premedicated with 4 mg dexamethasone or 20 mg piroxicam or 20 mg prednisolone were 5.3 times, 3.4 times and 2.5 times less compared to the placebo, respectively.
METHODS: A prospective, double-blinded randomized controlled trial comparing the post-operative pain score between BSCPB and LWI was conducted among patients undergoing thyroid surgery. Ropivacaine 0.50% was used in the study. Pain score was measured at 4, 12, 16 and 24 h after surgery using the visual analog scale (VAS). Subcutaneous injection of Tramadol was given whenever the pain score was ≥4 or requested by patients.
RESULTS: A total of 70 patients were recruited, with 35 patients on each arm. There was no statistical difference in the post-operative pain score between the two groups at 4 h (p = 0.208), 12 h (p = 0.860), 16 h (p = 0.376) and 24 h (p = 0.375) after surgery. Time to the first rescue dose of Tramadol between the two arms was also insignificant (p = 0.949). One patient in the BSCPB arm developed transient left upper limb weakness, which resolved 12 h after surgery.
CONCLUSION: LWI remains the simplest, safest and most economical method of pain management. While BSCPB is comparable, it does however, come with potential regional block related complications.
METHODS: This study enrolled patients (N = 36) who required root canal retreatment (RCR) on mandibular molar teeth, presented with periapical lesions with periapical index scores of 2 or 3, and had a pain visual analog scale (VAS) <50 and a percussion pain VAS <50. The participants were divided into 2 groups: (1) patients scheduled for RCR followed by LLLT (n = 18) and (2) patients scheduled for RCR followed by a mock LLLT (placebo) (n = 18). Postoperative pain was assessed using the VAS. Data were collected and statistically analyzed with the chi-square test, the independent sample t test, and the Mann-Whitney U test (P = .05).
RESULTS: On the first 4 days, postoperative pain significantly reduced in the LLLT group compared with the placebo group (P pain were found between the 2 groups after 5 and 7 days (P > .05). The number of patients who needed analgesics was lower in the LLLT group than in the placebo group (P pain during LLLT application.
CONCLUSIONS: LLLT may reduce postoperative pain after RCR of mandibular molars.
OBJECTIVES: To evaluate the evidence for the effectiveness of clonidine, when given as a premedication, in reducing postoperative pain in children less than 18 years of age. We also sought evidence of any clinically significant side effects.
SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 12, 2012), Ovid MEDLINE (1966 to 21 December 2012) and Ovid EMBASE (1982 to 21 December 2012), as well as reference lists of other relevant articles and online trial registers.
SELECTION CRITERIA: We included all randomized (or quasi-randomized), controlled trials comparing clonidine premedication to placebo, a higher dose of clonidine, or another agent when used for surgical or other invasive procedures in children under the age of 18 years and where pain or a surrogate (principally the need for supplementary analgesia) was reported.
DATA COLLECTION AND ANALYSIS: Two authors independently performed the database search, decided on the inclusion eligibility of publications, ascertained study quality and extracted data. They then resolved any differences between their results by discussion. The data were entered into RevMan 5 for analyses and presentation. Sensitivity analyses were performed, as appropriate, to exclude studies with a high risk of bias.
MAIN RESULTS: We identified 11 trials investigating a total of 742 children in treatment arms relevant to our study question. Risks of bias in the studies were mainly low or unclear, but two studies had aspects of their methodology that had a high risk of bias. Overall, the quality of the evidence from pooled studies was low or had unclear risk of bias. Four trials compared clonidine with a placebo or no treatment, six trials compared clonidine with midazolam, and one trial compared clonidine with fentanyl. There was substantial methodological heterogeneity between trials; the dose and route of clonidine administration varied as did the patient populations, the types of surgery and the outcomes measured. It was therefore difficult to combine the outcomes of some trials for meta-analysis.When clonidine was compared to placebo, pooling studies of low or unclear risk of bias, the need for additional analgesia was reduced when clonidine premedication was given orally at 4 µg/kg (risk ratio (RR) 0.24, 95% confidence interval (CI) 0.11 to 0.51). Only one small trial (15 patients per arm) compared clonidine to midazolam for the same outcome; this also found a reduction in the need for additional postoperative analgesia (RR 0.25, 95% CI 0.09 to 0.71) when clonidine premedication was given orally at 2 or 4 µg/kg compared to oral midazolam at 0.5 mg/kg. A trial comparing oral clonidine at 4 µg/kg with intravenous fentanyl at 3 µg/kg found no statistically significant difference in the need for rescue analgesia (RR 0.89, 95% CI 0.56 to 1.42). When clonidine 4 µg/kg was compared to clonidine 2 µg/kg, there was a statistically significant difference in the number of patients requiring additional analgesia, in favour of the higher dose, as reported by a single, higher-quality trial (RR 0.38, 95% CI 0.23 to 0.65).The effect of clonidine on pain scores was hard to interpret due to differences in study methodology, the doses and route of drug administration, and the pain scale used. However, when given at a dose of 4 µg/kg, clonidine may have reduced analgesia requirements after surgery. There were no significant side effects of clonidine that were reported such as severe hypotension, bradycardia, or excessive sedation requiring intervention. However, several studies used atropine prophylactically with the aim of preventing such adverse effects.
AUTHORS' CONCLUSIONS: There were only 11 relevant trials studying 742 children having surgery where premedication with clonidine was compared to placebo or other drug treatment. Despite heterogeneity between trials, clonidine premedication in an adequate dosage (4 µg/kg) was likely to have a beneficial effect on postoperative pain in children. Side effects were minimal, but some of the studies used atropine prophylactically with the intention of preventing bradycardia and hypotension. Further research is required to determine under what conditions clonidine premedication is most effective in providing postoperative pain relief in children.
DESIGN: Two-centre, randomised, controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis.
PARTICIPANTS: Seventy-two adults who had undergone cardiac surgery via a median sternotomy were included.
INTERVENTION: Participants were randomly allocated to one of two groups at 4 (SD 1) days after surgery. The control group received the usual advice to restrict their upper limb use for 4 to 6 weeks (ie, restrictive sternal precautions). The experimental group received advice to use pain and discomfort as the safe limits for their upper limb use during daily activities (ie, less restrictive precautions) for the same period. Both groups received postoperative individualised education in hospital and via weekly telephone calls for 6 weeks.
OUTCOME MEASURES: The primary outcome was physical function assessed by the Short Physical Performance Battery. Secondary outcomes included upper limb function, pain, kinesophobia, and health-related quality of life. Outcomes were measured before hospital discharge and at 4 and 12 weeks postoperatively. Adherence to sternal precautions was recorded.
RESULTS: There were no statistically significant differences in physical function between the groups at 4 weeks (MD 1.0, 95% CI -0.2 to 2.3) and 12 weeks (MD 0.4, 95% CI -0.9 to 1.6) postoperatively. There were no statistically significant between-group differences in secondary outcomes.
CONCLUSION: Modified (ie, less restrictive) sternal precautions for people following cardiac surgery had similar effects on physical recovery, pain and health-related quality of life as usual restrictive sternal precautions. Similar outcomes can be anticipated regardless of whether people following cardiac surgery are managed with traditional or modified sternal precautions.

[Katijjahbe MA, Granger CL, Denehy L, Royse A, Royse C, Bates R, Logie S, Nur Ayub MA, Clarke S, El-Ansary D (2018) Standard restrictive sternal precautions and modified sternal precautions had similar effects in people after cardiac surgery via median sternotomy ('SMART' Trial): a randomised trial. Journal of Physiotherapy 64: 97-106].
METHODS/DESIGN: This study is a phase II, double-blind, randomised controlled trial with concealed allocation, blinding of patients and assessors, and intention-to-treat analysis. Patients (n = 72) will be recruited following cardiac surgery via a median sternotomy. Sample size calculations were based on the minimal important difference (two points) for the primary outcome: Short Physical Performance Battery. Thirty-six participants are required per group to counter dropout (20%). All participants will be randomised to receive either standard or modified sternal precautions. The intervention group will receive guidelines encouraging the safe use of the upper limbs. Secondary outcomes are upper limb function, pain, kinesiophobia and health-related quality of life. Descriptive statistics will be used to summarise data. The primary hypothesis will be examined by repeated-measures analysis of variance to evaluate the changes from baseline to 4 weeks post-operatively in the intervention arm compared with the usual-care arm. In all tests to be conducted, a p value <0.05 (two-tailed) will be considered statistically significant, and confidence intervals will be reported.
DISCUSSION: The Sternal Management Accelerated Recovery Trial (S.M.A.R.T.) is a two-centre randomised controlled trial powered and designed to investigate whether the effects of modifying sternal precautions to include the safe use of the upper limbs and trunk impact patients' physical function and recovery following cardiac surgery via median sternotomy.

AIMS: This study was done to find out the most suitable anaesthesia for patients with fewer complications and also to look at the trend of anaesthesia being used.
METHODS: A retrospective analysis was done of patients who underwent cataract surgery from 2007 to 2014 in Hospital Melaka. Data were obtained from the National Eye Database and analysed using SPSS. Trend of types of anaesthesia used and the associated complications with each were studied.
RESULTS: The most frequently used anaesthesia was topical anaesthesia, which showed an upward trend followed by subtenon in turn showing a downward trend. Subtenon anaesthesia was associated with more intraoperative and postoperative complications while topical anaesthesia was associated with fewer complications.
CONCLUSIONS: Topical anaesthesia has shown a steady increase in usage and is the ideal anaesthesia, which has been associated with fewer complications.
METHODS: Databases including MEDLINE, EMBASE, and CENTRAL were comprehensively searched from their inception until March 2023. The inclusion criteria covered all Randomized Clinical Trials (RCTs) and observational studies comparing dexmedetomidine to control in adult patients undergoing renal transplant surgery. Exclusions comprised case series and case reports.
RESULTS: Ten RCTs involving a total of 1358 patients met the eligibility criteria for data synthesis. Compared to the control group, the dexmedetomidine group demonstrated a significantly lower incidence of delayed graft function (OR = 0.71, 95% CI 0.52-0.97, p = 0.03, GRADE: Very low, I2 = 0%). Dexmedetomidine also significantly prolonged time to initiation of rescue analgesia (MD = 6.73, 95% CI 2.32-11.14, p = 0.003, GRADE: Very low, I2 = 93%) and reduced overall morphine consumption after renal transplant (MD = -5.43, 95% CI -7.95 to -2.91, p < 0.0001, GRADE: Very low, I2 = 0%). The dexmedetomidine group exhibited a significant decrease in heart rate (MD = -8.15, 95% CI -11.45 to -4.86, p < 0.00001, GRADE: Very low, I2 = 84%) and mean arterial pressure compared to the control group (MD = -6.66, 95% CI -11.27 to -2.04, p = 0.005, GRADE: Very low, I2 = 87%).
CONCLUSIONS: This meta-analysis suggests that dexmedetomidine may potentially reduce the incidence of delayed graft function and offers a superior analgesia profile as compared to control in adults undergoing renal transplants. However, the high degree of heterogeneity and inadequate sample size underscore the need for future adequately powered trials to confirm these findings.
