Randomized Controlled Trial
Subcutaneous ketamine for postoperative pain relief in Rwanda: a randomized clinical trial.
Postoperative pain control is often inadequate in low-income countries such as Rwanda, prompting the search for an inexpensive improvement. A randomized controlled trial was conducted to study the use of subcutaneous ketamine for the management of postoperative pain in patients undergoing major surgery in Kigali, Rwanda. ⋯ Results of this study in Kigali, Rwanda showed that subcutaneous administration of ketamine 1 mg·kg-1 twice daily, in addition to standard postoperative care, produced a small improvement in postoperative pain but resulted in more minor side effects TRIAL REGISTRATION: www.clinicaltrials.gov (NCT02514122). Registered 31 July 2015.

Randomized Controlled Trial Comparative Study
Nitrous oxide added at the end of isoflurane anesthesia hastens early recovery without increasing the risk for postoperative nausea and vomiting: a randomized clinical trial.
Nitrous oxide (N2O) has been reported to increase the risk of postoperative nausea and vomiting (PONV) in a dose-dependent manner. We investigated the effect of adding N2O at the end of isoflurane inhalational anesthesia on the recovery and incidence of PONV. Our hypothesis was that N2O would reduce the time to early recovery without increasing the incidence of PONV. ⋯ Adding N2O during the last 30 min of an isoflurane-based inhalational anesthetic reduced the time to extubation, eye opening, and orientation.

The anterior iliac crest (AIC) is one of the most common sites for harvesting autologous bone, but the associated postoperative pain can result in significant morbidity. Recently, the transmuscular quadratus lumborum block (TQL) has been described to anesthetize the thoraco-lumbar nerves. This study utilizes a combination of cadaveric models and clinical case studies to evaluate the dermatomal coverage and analgesic utility of TQL for AIC bone graft donor site analgesia. ⋯ Ultrasound-guided TQL injections consistently cover the thoraco-lumbar innervation relevant to the AIC graft donor site. The injectate spread seen in anatomical dissections correlated with the dermatomal anesthesia clinically. The TQL has the potential to provide reliable analgesia for patients undergoing AIC bone graft harvesting.
