We present the case report of a 49-year-old gentleman with a history of adenoid cystic carcinoma of the left nare status post curative bifrontal craniotomy, left lateral rhinotomy and medial maxillectomy, adjuvant radiotherapy, and orbital exenteration for optic neuropathy, complicated by medial wall dehiscence. His course was also complicated by severe radiation trismus, for which he was scheduled to undergo bilateral mandibular coronoidectomies. ⋯ Because of concerns of traumatizing his nare, we utilized a flexible fiberoptic bronchoscope to perform asleep transorbital intubation. Airway management in patients with severe trismus may require ingenuity.

To determine risk factors associated with reintubations in adult patients with soft tissue infections. ⋯ Soft tissue patients who have received rocuronium are at increased risk for reintubation, particularly those with renal failure. In addition, this article supports the use of neuromuscular blockade reversals, even in patients with a strong train of four ratio.

Perioperative hypothermia is a frequently observed phenomenon of general anesthesia and is associated with adverse patient outcome. Recently, a significant influence of core temperature before induction of anesthesia has been reported. However, there are still little existing data on core temperature before induction of anesthesia and no data regarding potential risk factors for developing preoperative hypothermia. The purpose of this investigation was to estimate the incidence of hypothermia before anesthesia and to determine if certain factors predict its incidence. ⋯ As a consequence of the high incidence of hypothermia before anesthesia, measuring core temperature should be mandatory 60 to 120minutes before induction to identify and provide adequate treatment to hypothermic patients.

Randomized Controlled Trial
Dose-ranging effect of systemic diphenhydramine on postoperative quality of recovery after ambulatory laparoscopic surgery: a randomized, placebo-controlled, double-blinded, clinical trial.
Diphenhydramine is an antihistamine with previously demonstrated analgesic and antiemetic properties. However, it is unknown if the beneficial perioperative properties of diphenhydramine can translate to a better quality of postsurgical recovery. The main objective of the current investigation was to investigate dose-ranging effects of diphenhydramine on quality of recovery after surgery. ⋯ Diphenhydramine does not provide dose-ranging improvements on postoperative quality of recovery after ambulatory laparoscopic gynecologic surgery. Our results support a recent concept that not all postoperative nausea and vomiting symptoms are clinically important. Future studies evaluating postoperative nausea and vomiting should include patient-centered outcomes to validate the clinical importance of the examined interventions.

Randomized Controlled Trial Comparative Study
Magnesium sulfate or diltiazem as adjuvants to total intravenous anesthesia to reduce blood loss in functional endoscopic sinus surgery.
This study was designed to know whether addition of magnesium sulfate (MgSO4) or diltiazem to total intravenous anesthesia (TIVA) (propofol) aided reduction in blood loss during functional endoscopic sinus surgery (FESS). The secondary outcomes measured were surgeon's assessment of the surgical field and hemodynamics. ⋯ It was concluded that the addition of both MgSO4 and diltiazem to TIVA propofol results in significant reduction in blood loss and significant improvement in the quality of surgical field during FESS without causing any adverse effects on the hemodynamics or on the recovery from anesthesia. The surgical field in the MgSO4 group was significantly better than that in the diltiazem group (P=.04).
