Randomized Controlled Trial Comparative StudyFosaprepitant versus ondansetron for the prevention of postoperative nausea and vomiting in patients who undergo gynecologic abdominal surgery with patient-controlled epidural analgesia: a prospective, randomized, double-blind study.
Postoperative nausea and vomiting (PONV) is the most common postoperative complication. The postoperative use of opioids is known to increase the incidence. We compared fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, and ondansetron for their preventive effects on PONV in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia. ⋯ Compared to ondansetron, fosaprepitant more effectively decreased the incidence of vomiting in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia.

Dextrocardia, a term used to describe all varieties of developmental malformations resulting in the positioning of the heart in the right hemithorax, is linked to a number of highly significant cardiac disorders. Current estimates vary tremendously in the literature. Only about 10 % of patients with diagnosed dextroversion show no substantial cardiac pathology; however, the incidence of congenital heart defects associated with dextrocardia is close to 100 %. ⋯ In summary, heart malposition is a group of complex pathologic associations within the human body, rather than just a single congenital defect. Clinicians such as anesthesiologists have unique challenges managing patients with dextrocardia. An appreciation of associated pathogenesis, appropriate diagnosis, and management is paramount in ensuring the best outcome for these patients perioperatively.

Randomized Controlled TrialEffect of ondansetron on post-dural puncture headache (PDPH) in parturients undergoing cesarean section: a double-blind randomized placebo-controlled study.
One of the most exhausting complications of spinal anesthesia, especially in parturients, is post-dural puncture headache (PDPH). This headache is not responsive to the usual pain killers. Ondansetron is a 5-HT3 receptor antagonist which is generally used for the prophylactic management of nausea and vomiting; however, studies have found that ondansetron might decrease the incidence of PDPH. Therefore, we aimed to evalute the effect of ondansetron on decreasing the incidence of PDPH. ⋯ Ondansetron (0.15 mg/kg) appeared to reduce the incidence of PDPH, as well as the incidence of hypotension and PONV, in parturients undergoing spinal anesthesia for cesarean section.

Observational StudyEstimation of the success rate of anesthetic management for thymectomy in patients with myasthenia gravis treated without muscle relaxants: a retrospective observational cohort study.
Although maintaining anesthesia for myasthenia gravis (MG) with minimal muscle relaxants (MR) is common, the success rate of anesthetic management for MG without MR is not clear. We therefore retrospectively examined the success rate of anesthetic management for MG without MR among 66 consecutive cases of thymectomy for MG performed at our hospital between January 2004 and April 2010, before approval of using sugammadex. A total of 60 patients (90.9 %) were treated without MR (N group). ⋯ The reasons for using MR included coughing at intubation in one case, bucking during surgery in two cases, and MR was considered to be safer by the attending anesthesiologist in three cases. The number of cases of impossible extubation requiring ventilation on that day was three in the N group and none in the R group. Finally, the success rate of anesthetic management for MG without MR was estimated to be 71.1 % (95 % CI: 65.9-77.5 %).
