Randomized Controlled Trial Comparative Study
Remifentanil for the insertion and removal of long-term central venous access during monitored anesthesia care.
To determine the analgesic efficacy of three different rates of remifentanil infusion in patients undergoing insertion or removal of long-term central venous access devices during monitored anesthesia care and local anesthetic field infiltration. ⋯ For the insertion or removal of long-term central venous access devices, all three remifentanil infusion rates proved to be equally analgesic-efficient. However, the excessive sedation and tendency to respiratory and cardiovascular events associated with the highest remifentanil infusion rate renders such a rate less desirable for this purpose.

To investigate whether a common single nucleotide polymorphism (SNP), rs10494366, is associated with significant prolongation of the QTc interval following administration of 5-HT(3)-receptor antagonists in the perioperative setting. ⋯ Homozygous and heterozygous carrier status for the major SNP, rs10494366 allele (T), in intron 1 of the human NOSA1P gene may be associated with an increased risk of QTc interval prolongation following administration of 5-HT(3)-receptor antagonists in the perioperative setting, when compared with homozygotes for the minor (G) allele.

The ultrasound-guided transversus abdominis plane (TAP) block is a useful tool in controlling postoperative pain following abdominal surgery. The bilateral ultrasound-guided TAP blocks successfully managed the pain of a patient presenting with hypoxemia and respiratory failure in the Post-anesthesia Care Unit, following a laparotomy for small bowel obstruction during general anesthesia. The TAP block reduced systemic opioid requirements and opioid-induced sedation and respiratory depression, improved patient compliance with non-invasive positive pressure ventilation, and prevented the need for intubation and ventilation in the intensive care unit.

Case Reports
Delayed awakening following inadvertent high-dose remifentanil infusion in a 13 year old patient.
We report the case of a 13 year old patient who received 3.0 mg of remifentanil during a 50-minute surgical procedure as a result of a dosage miscalculation. The patient failed to awaken at the conclusion of the procedure and showed signs of opioid overdose. She recovered spontaneously two hours later.

Case Reports
Perioperative management of partial face transplantation involving a heparin antibody-positive donor.
Heparin-induced thrombocytopenia (HIT) is an immunologic condition that may lead to thrombosis. We present a case of face transplantation from a donor who had suffered a severe stroke, possibly from HIT, during cardiac surgery. The procedure was planned to include full heparinization. The anesthesia team was involved in the early planning phase and had detailed access to the donor's medical history; alternative anticoagulation for the donor and recipient was suggested so as to avoid a possible complication.
