Meta AnalysisSide Effect Rates of Opioids in Equianalgesic Doses Via Intravenous Patient-Controlled Analgesia: A Systematic Review and Network Meta-analysis.
Why is this important?
Despite growth of regional and non-opioid analgesic options, opioids remain the mainstain of peri-operative management of moderate to severe pain. IV patient-controlled analgesia (PCA) is a safe, common and reliable delivery mechanism.
What did they do?
Dinges et al. performed a network meta-analysis of 63 studies covering 16 different PCA opioids, comparing side-effects at equianalgesic doses. Morphine was used as the baseline comparator.
And they found?
Although there were some small difference in the incidence of nausea & vomiting (fentanyl having lowest N&V risk, buprenorphine highest) and pruritus (nalbuphine, butorphanol, methadone, and pethidine/meperidine resulting in least pruritis), there were significant differences for sedation and satisfaction.
Pethidine/meperidine, fentanyl & oxymorphone showed the lowest sedation scores, although respiratory depression events were too infrequent to show differences. Oxycodone, alfentanil, remifentanil, fentanyl & pethidine/meperidine resulted in the highest patient satisfaction and tramadol was the least satisfying.
Take-home message
Although some PCA-opioids perform better than others in small ways, overall side-effect profiled are very similar and comparably safe. Oxycodone, alfentanil and remifentanil however result in significantly higher patient satisfaction.
The big picture...
Rather than focusing on the small differences among opioids, there is almost certainly more to be gained by a disciplined, multi-modal analgesic focus that reduces opioid use and thus side-effects.

Meta AnalysisPerioperative Dextrose Infusion and Postoperative Nausea and Vomiting: A Meta-analysis of Randomized Trials.
Perioperative IV dextrose infusions have been investigated for their potential to reduce the risk of postoperative nausea and vomiting. In this meta-analysis, we investigated the use of an intraoperative or postoperative infusion of dextrose for the prevention of postoperative nausea and vomiting. ⋯ The use of perioperative dextrose did not result in a statistically significant association with postoperative nausea and vomiting. When utilized, plasma glucose monitoring is recommended to assess for postoperative hyperglycemia. Further prospective trials are necessary to examine the potential impact of timing of administration of a dextrose infusion on incidence of postoperative nausea and vomiting and rescue antiemetic requirements.

ReviewApplying Conflict Management Strategies to the Pediatric Operating Room.
Effective communication is essential in today's health care environment, and poor communication can lead to conflict among health care providers. Differences in cultures and beliefs can further incite conflict among health care team members, families, and patients. Pediatric patient care has a higher potential for conflict because decision-making responsibilities are shared among patients, parents/guardians, and clinicians. ⋯ Aligning the interests of the parties involved in conflict will encourage collaborative problem solving. Cultural competency training can improve communication and conflict management skills. Effective conflict management through formal education of all perioperative team members can lead to improved communication and teamwork and better patient outcomes.

ReviewControversies in the Postoperative Management of the Critically Ill Heart Transplant Patient.
Heart transplant recipients are susceptible to a number of complications in the immediate postoperative period. Despite advances in surgical techniques, mechanical circulatory support (MCS), and immunosuppression, evidence supporting optimal management strategies of the critically ill transplant patient is lacking on many fronts. This review identifies some of these controversies with the aim of stimulating further discussion and development into these gray areas.

ReviewFocused Cardiac Ultrasound in the Pediatric Perioperative Setting.
Focused cardiac ultrasonography (FoCUS) has become an important diagnostic tool for acute care physicians. FoCUS allows real-time visualization of the heart and, in combination with the physical examination, acts as a hemodynamic monitor to manage patient care in acute situations. Most of the available perioperative literature has focused on adult patients. ⋯ Barriers to implementation by pediatric intensivists and emergency medicine physicians include a lack of understanding of indications and training opportunities in pediatric FoCUS. It is likely that similar barriers exist in pediatric anesthesiology resulting in underutilization of FoCUS. The use of FoCUS in the pediatric operating room, however, may positively impact care of infants and children and should be encouraged.
