Randomized Controlled TrialEffect of remifentanil on post-operative analgesic consumption in patients undergoing shoulder arthroplasty after interscalene brachial plexus block: a randomized controlled trial.
Remifentanil is useful in balanced anesthesia; however, there is concern regarding opioid-induced hyperalgesia. The effect of remifentanil on rebound pain, characterized by hyperalgesia after peripheral nerve block has rarely been studied. This study evaluated whether intraoperative remifentanil infusion may increase postoperative analgesic requirement in patients receiving preoperative interscalene brachial plexus block (IBP). ⋯ Remifentanil administration during arthroscopic shoulder surgery in patients undergoing preoperative IBP increased postoperative analgesic consumption.

Randomized Controlled TrialOxytocin infusion rates for maintaining uterine tone during non-elective cesarean section in laboring patients: a randomized, controlled trial.
Oxytocin infusions for uterine tone maintenance are recommended following initial low oxytocin doses during cesarean section. Very limited literature is available on the optimal infusion rates in laboring patients who have been earlier exposed to oxytocin. ⋯ Oxytocin infusions at 5 IU/h and 10 IU/h are more effective in reducing blood loss and preventing PPH than 2.5 IU/h. The dose of 10 IU/h, although the most efficacious, is associated with a high incidence of side effects. Hence, further studies are needed to find out the optimal maintenance infusion rate of oxytocin during cesarean section in laboring patients who have received oxytocin earlier.

Evaluation of 254 cesarean sections with COVID-19 in terms of anesthesia and clinical course: 1-year experience.
The study aims to compare anesthesia methods, clinical course, and maternal and fetal outcomes of symptomatic and asymptomatic pregnant women undergoing cesarean operation with confirmed COVID-19. ⋯ Close follow-up of the laboratory values and comorbidities (especially asthma) of pregnant will provide information about the clinical course as in other patient groups. Spinal anesthesia is a safe and sufficient anesthesia method in both symptomatic and asymptomatic COVID-19 pregnant women when performed by experienced hands.

Preoperative and postoperative complications of cerebrospinal fluid drainage in descending thoracic and thoraco-abdominal aortic aneurysm surgery: a single-center retrospective study.
Cerebrospinal-fluid drainage (CSFD) has been performed to prevent paraplegia in descending thoracic or thoraco-abdominal aortic aneurysm (DTA/TAAA) surgery; however, CSFD itself has a risk of severe complications. We retrospectively investigated the incidence rates of CSFD-related preoperative and postoperative complications. ⋯ Bloody cerebrospinal fluid and meningitis, which are severe complications associated with spinal puncture, occurred within 1 day after spinal puncture. The incidence rates of moderate/mild complications were high in both the preoperative and postoperative periods. These results showed that CSFD catheter insertion and management should be performed carefully with consideration given to the risks and benefits of CSFD.
