This preliminary investigation attempted to determine the effectiveness of egg membranes as a new biological dressing to promote infection-free healing and provide pain relief over split-thickness skin graft (STSG) donor sites. ⋯ From this preliminary study, egg membrane may be an ideal STSG donor site dressing, as it possesses properties of pain relief, wound protection, promotion of healing, and low cost. However, the limited unit size must be overcome, and its clinical application for burn wounds should be studied.

The posterior lumbar interbody fusion (PLIF) procedure allows restoration of the weight-bearing capacity to a more physiological ventral position and maintenance of disc space height. However, the procedure can be technically difficult and may cause complications. It has always been performed bilaterally with paired cages; a single central cage has not been commonly used. ⋯ The PLIF procedure using a single, central cage combined with bilateral pedicle screws fixation obtained satisfactory outcome within a short-term or long-term follow-up period. Since the implant-related complications have seldom been observed, it may be used as an alternative option for recurrent lumbar disc herniation or low grade spondylolisthesis with apparent degenerative disc disease.

Case Reports
Anesthetic management of a parturient undergoing cesarean section with a tracheal tumor and hemoptysis.
Anesthetic management of a parturient with respiratory failure associated with hemoptysis, dyspnea, and orthopnea is difficult. An anesthesiologist should realize that the patient's major problem is not solved during the surgery. This circumstance is similar to a patient with associated cardiac disease scheduled for non-cardiac surgery. ⋯ A decrease in cough strength, as well as dyspnea, orthopnea, and hyperventilation may be harmful to both the parturient and the fetus. However, we successfully managed this case using epidural anesthesia combined with assisted mask ventilation instead of spontaneous breathing usually provided by a simple mask in almost all American Society of Anesthesiology (ASA) class I-II parturients during cesarean section. The anesthetic level was maintained at T8 with 18 ml of 2% Xylocaine mixed with 2 ml of 7% sodium bicarbonate with 1:200,000 epinephrine epidurally and with the patient in a supine position with the head up at 30 degrees to prevent cephalic spreading and to ensure better pulmonary ventilation.

Rapid-sequence induction with cricoid pressure is a standard procedure for inducing anesthesia in patients with a potentially full stomach. During the induction period, if the patient develops generalized movements of the body, the pressure level of the cricoid may change unexpectedly. As a result, the increase in intragastric pressure may cause gastric regurgitation and consequent pulmonary aspiration. ⋯ However, most patients who received rocuronium complained of severe burning pain in their arm during intravenous injection. Even after the administration of the induction agents, rocuronium injection can also cause withdrawal of the hand or other generalized movements of the body. We describe a case of gastric regurgitation with pulmonary aspiration following generalized spontaneous movements associated with rocuronium injection in a girl who received pediatric emergent surgery.

Secondary aortoenteric fistula (SAF) is now recognized as an uncommon but exceedingly important complication of abdominal aortic reconstruction. The complication often occurs months to years after the original surgery. The main clinical manifestation of the disease is always upper gastrointestinal bleeding. ⋯ Even immediate exploratory laparotomy was performed, the patient died 48 hrs after the surgical management. Because of the increasing number of elective aortic aneurysm repairs in the aging population, it is likely that more patients with SAF will present to the clinical physicians in the future. So, a high index of suspicion is necessary for prompt diagnosis and treatment of this actually life-threatening event.
