Case Reports
General anesthesia for cesarean section in a parturient with a single ventricle and pulmonary atresia.
The successful management of a cesarean section in a parturient with a single ventricle and pulmonary atresia using general anesthesia is discussed. After cyanosis at birth, the patient underwent cardiac catheterization, which showed an apparent severe tetralogy of Fallot, atresia of the main pulmonary artery (PA), and a large patent ductus arteriosus. When she was 7 months of age, a Blalock-Taussig shunt (right subclavian artery to right PA) was done. ⋯ The patient was then taken to the operating room electively, and an opioid-based general anesthetic was administered. Both mother and infant did well. This case is presented because the physiology of the patient's lesion and her unusual social history presented challenges for her anesthetic management.

To evaluate the success of epidural anesthesia for postpartum tubal ligation using epidural catheters placed during labor and to determine whether patient characteristics, timing of surgery, or technical factors (e.g., length of epidural catheter inserted into the epidural space) influenced the success of subsequent epidural anesthesia. ⋯ Although other factors may influence the timing of postpartum tubal ligation after delivery, the success of epidural anesthesia for tubal ligation using in situ epidural catheters is greater if surgery is performed shortly after delivery.

Randomized Controlled Trial Comparative Study Clinical Trial
Spinal or systemic analgesia after extensive spinal surgery: comparison between intrathecal morphine and intravenous fentanyl plus clonidine.
To compare two different methods of postoperative analgesia after extensive spinal fusion. ⋯ This study shows that there is a major risk of respiratory depression with a single intrathecal dose of morphine 0.3 mg to control postoperative pain after scoliosis surgery. Systemic clonidine-fentanyl may be a possible approach to the postoperative pain treatment of this surgery.

We report an unusual case of endotracheal tube obstruction secondary to alteration of the preoperative fasting period. A patient scheduled for coronary artery bypass grafting had been instructed to take nothing by mouth except scheduled medication with sips of water prior to surgery. Induction of anesthesia and tracheal intubation were accomplished without incident. ⋯ We believe that the mass of gum caused enough deviation of the endotracheal tube to impair ventilation. The safety of preoperative gum chewing and liquid ingestion is discussed. Other incidents of anesthetic problems caused by modification of the traditional preoperative fast are highlighted.
