Randomized Controlled Trial
Comparisons of surgical conditions of deep and moderate neuromuscular blockade through multiple assessments and the quality of postoperative recovery in upper abdominal laparoscopic surgery.
To determine the effect of deep neuromuscular blockade (NMB) on surgical field conditions through multiple assessments during pneumoperitoneum and evaluate the effect of the depth of intraoperative NMB on the quality of postoperative recovery over multiple time periods. ⋯ Multiple assessments of the surgical field condition demonstrated that deep NMB provided a more satisfactory surgical field condition than moderate NMB during laparoscopic gastrectomy. However, the quality of postoperative recovery, assessed using the PostopQRS, was not different between the two groups according to the depth of NMB.

To determine 30-day-mortality, incidence and characteristics of perioperative cardiac arrest as well as the respective independent risk factors in preterm infants undergoing non-cardiac surgery. ⋯ 30-day-mortality and the incidence of perioperative cardiac arrest of preterms undergoing non-cardiac surgery were higher than previously reported. The identified independent risk factors may improve interdisciplinary perioperative risk assessment, optimal preoperative stabilization and scheduling of optimal surgical timing.

In the upcoming years there will be a growing number of elderly patients requiring general anaesthesia. As age is an independent risk factor for postoperative delirium (POD) the incidence of POD will increase concordantly. One approach to reduce the risk of POD would be to avoid excessively high doses of anaesthetics by using neuromonitoring to guide anaesthesia titration. Therefore, we evaluated the influence of patient's age on various electroencephalogram (EEG)-based anaesthesia indices. ⋯ Almost all current neuromonitoring devices are influenced by age, with the potential to result in inappropriately high dosage of anaesthetics. Therefore, anaesthesiologists should be aware of this phenomenon, and the next generation of monitors should correct for these changes.

To evaluate the effectiveness of preoperative gabapentinoid administration. ⋯ The preoperative use of pregabalin and gabapentin, up to doses of 75 and 300 mg respectively, mitigates the risks of hospital readmission and postoperative respiratory complications which can in part be explained by lower intraoperative opioid use. Further research is warranted to elucidate mechanisms of the preventive action.
