Adding the μ-opioid receptor agonist remifentanil to agents used to induce general anaesthesia in electroconvulsive therapy (ECT) can reduce the required doses of induction agents and their unfavourable effects on seizure threshold and quality. However, whether remifentanil has favourable long-term treatment effects in terms of response and remission rates, speed of response and remission, and side-effects has not been studied. ⋯ The use of adjunctive remifentanil was associated with more short-term side-effects and no favourable long-term clinical outcomes. The practice of routinely adding remifentanil to barbiturate anaesthesia should therefore be reconsidered.

The African Surgical Outcomes Study (ASOS) showed that surgical patients in Africa have a mortality twice the global average. Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications. ⋯ NCT03044899.

Review Meta Analysis
Neuroprotection by anaesthetics in rodent models of traumatic brain injury: a systematic review and network meta-analysis.
Anaesthetic neuroprotection in the setting of traumatic brain injury (TBI) remains unproved and is based upon the results in preclinical experiments. Here, we sought to synthesise the results in rodent models of TBI, and to evaluate the effects of publication bias, experimental manipulation, and poor study quality on the effect estimates. ⋯ Anaesthetics do provide neuroprotection in rodent models of TBI. The effect-size estimates do not appear to be exaggerated by selective publication, experimental manipulation, or study design. The main shortcoming of the included studies were small sample sizes leading to low power and imprecision, which precluded the network meta-analysis from providing a meaningful ranking for efficacy amongst the drugs. Reliable preclinical investigations of neuroprotection by anaesthetics will require larger sample sizes.
