Review Meta Analysis
Metoclopramide for nausea and vomiting prophylaxis during and after Caesarean delivery: a systematic review and meta-analysis.
Nausea and vomiting occur commonly during and after Caesarean delivery (CD) performed under neuraxial anaesthesia. Metoclopramide is a prokinetic agent reported to be safe in parturients. This meta-analysis assesses the efficacy of metoclopramide for prophylaxis against intra- and postoperative nausea and vomiting (IONV and PONV) in parturients undergoing CD under neuraxial anaesthesia. ⋯ Extra-pyramidal side-effects were not reported in any patient. In conclusion, this review suggests that metoclopramide is effective and safe for IONV and PONV prophylaxis in this patient population. Given the quality of the studies and the infrequent use of neuraxial opioids, these results should be interpreted with caution in current practice and further studies are needed to confirm those findings.

Meta Analysis
Oxycodone clearance is markedly reduced with advancing age: a population pharmacokinetic study.
Oxycodone is a µ-opioid receptor agonist, the global use of which has increased vigorously during the past decade. The pharmacokinetic data of oxycodone available for elderly are limited, and there appear to be only little data on the population pharmacokinetics of oxycodone. ⋯ Age was found to be a significant covariate for oxycodone pharmacokinetics. In elderly patients, dosing should therefore be reduced and carefully titrated to avoid considerable accumulation of oxycodone and potentially hazardous side-effects.
