Randomized Controlled Trial Comparative StudyEffect of local anesthetic volume (20 mL vs 30 mL ropivacaine) on electromyography of the diaphragm and pulmonary function after ultrasound-guided supraclavicular brachial plexus block: a randomized controlled trial.
Diaphragmatic paralysis following supraclavicular brachial plexus block (SCBPB) is ascribed to phrenic nerve palsy. This study investigated the effect of 2 volumes of 0.375% ropivacaine on efficacy of block as a surgical anesthetic and as an analgesic and examined diaphragm compound muscle action potentials (CMAPs) and pulmonary function before and after SCBPB. ⋯ The incidence rates of phrenic nerve palsy and diaphragm paralysis were reduced, and lung function was less impaired in patients who received 20 mL vs 30 mL of 0.375% ropivacaine without any differences in block success. Selecting a lower volume of anesthetic for nerve block may be especially beneficial in obese patients or patients with cardiopulmonary disease.

Implementation of an enhanced recovery program in pediatric laparoscopic colorectal patients does not worsen analgesia despite reduced perioperative opioids: a retrospective, matched, non-inferiority study.
Enhanced recovery protocols (ERPs) decrease length of stay and postoperative morbidity, but it is important that these benefits do not come at a cost of sacrificing proper perioperative analgesia. In this retrospective, matched cohort study, we evaluated postoperative pain intensity in pediatric patients who underwent laparoscopic colorectal surgeries before and after ERP implementation. ⋯ Implementation of our ERP for pediatric laparoscopic colorectal patients was associated with less perioperative opioids without worsening postoperative pain scores. In addition, patients who received the protocol had faster return of bowel function, shorter postoperative hospital stays, and a lower rate of 30-day hospital readmissions. In pediatric laparoscopic colorectal patients, the incorporation of an ERP was associated with a pronounced decrease in perioperative morbidity without sacrificing postoperative analgesia.
