Music Interventions in Pediatric Surgery (The Music Under Surgery In Children Study): A Randomized Clinical Trial.
Perioperative music interventions have been shown to reduce anxiety and pain in adults. This inexpensive, easily applicable intervention could be of benefit to children as well. Our objective was to determine the effects of music interventions on distress, anxiety, and postoperative pain in infants undergoing surgery. ⋯ Music interventions do not seem to benefit all young infants undergoing surgery. The potential benefits of music interventions in the preoperative period and in more distressed children warrant further exploration.

Total mesorectal excision (TME) gives excellent oncological results in rectal cancer treatment, but patients may experience functional problems. A novel approach to performing TME is by single-port transanal minimally invasive surgery. This systematic review evaluated the functional outcomes and quality of life after transanal and laparoscopic TME. ⋯ No differences in function were observed between transanal and laparoscopic TME.

The basic perineural catheter design has changed minimally since inception, with the catheter introduced through or over a straight needle. The U.S. Food and Drug Administration recently cleared a novel perineural catheter design comprising a catheter attached to the back of a suture-shaped needle that is inserted, advanced along the arc of its curvature pulling the catheter past the target nerve, and then exited through the skin in a second location. The authors hypothesized that analgesia would be noninferior using the new versus traditional catheter design in the first two days after painful foot/ankle surgery with a primary outcome of average pain measured with the Numeric Rating Scale. ⋯ Suture-type perineural catheters provided noninferior analgesia compared with traditional catheters for continuous popliteal-sciatic blocks after painful foot and ankle surgery. The new catheter design appears to be a viable alternative to traditional designs used for the past seven decades.

Peri-operative fasting guidelines allow clear fluids including tea without milk to be consumed up to 2 h before surgery. Recent evidence has shown that a modest amount of milk consumed with clear fluids does not significantly slow gastric emptying. ⋯ The change of gastric antrum CSA after 250 ml of tea with milk is similar to a corresponding volume of water in fasted pregnant patients. This study could help inform future peri-operative fasting guidelines regarding the use of a modest volume of milk with clear fluids.

Pneumoperitoneum for laparoscopic surgery is associated with a rise of driving pressure. The authors aimed to assess the effects of positive end-expiratory pressure (PEEP) on driving pressure at varying intraabdominal pressure levels. It was hypothesized that PEEP attenuates pneumoperitoneum-related rises in driving pressure. ⋯ Transpulmonary driving pressure rises with an increase in intraabdominal pressure, an effect that can be counterbalanced by targeted PEEP. Future studies have to elucidate which combination of PEEP and intraabdominal pressure is best in term of clinical outcomes.
