PRESENTATION OF CASE: We report three cases of extraluminal fish bone migration with diverse clinical presentations and complications. The first patient had mild throat symptoms and a fish bone that travelled through the neck and migrated towards the subcutaneous tissue without causing complications. The second patient developed deep neck abscess and thoracic complications as a result of the migrated foreign body, but recovered after surgical exploration and foreign body removal. The third patient presented late in sepsis and upper airway obstruction, subsequently succumbed to multiorgan failure before any surgical intervention.
DISCUSSION: Thorough physical and endoscopy examinations are essential in patients with fish bone ingestion. Normal endoscopic findings in a symptomatic patient should always raise the suspicion of a migrated fish bone. A radiographic imaging study is often helpful in locating the foreign body and potential complications. The migrated fish bone that acts as the source of infection in the neck should be traced and removed surgically. The resulting abscess, if present, must be drained. The management of a migrated fish bone can be challenging and often require multi-discipline collaboration.
CONCLUSION: The migration of the ingested fish bone outside the upper aerodigestive tract can cause serious complications and death in some cases. Clinicians should always maintain a high level of suspicion towards extraluminal migration in a patient with a history of fish bone ingestions but normal endoscopic findings. We emphasize the importance of early recognition and prompt surgical intervention to remove the migrated fish bone to minimise the potential morbidity and mortality.
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
