Review Case ReportsInterdisciplinary rounds in the postanesthesia care unit: a new perioperative paradigm.
Patients in the perioperative and postanesthesia care unit (PACU) experience several transitions in patient care at the same time that the majority of major morbidities will arise. The transitions for these patients are at the critical juncture between surgery and a steady sustained recovery. Historically these important medical problems have been addressed as a nonformalized process. The authors have introduced a formalized process, based on interdisciplinary rounding strategies used in intensive care units, to attend patients and address problems.

Postoperative anxiety has received less attention historically than preoperative anxiety. Recognition that anxiety occurs throughout the perioperative period has led to increased interest in identifying and treating anxiety in the postoperative period. This article outlines the causes of postoperative anxiety, how it is classified, the effects of anxiety on outcomes after surgery, and some of the clinical procedures that produce the highest levels of anxiety for patients. In addition, an attempt is made to delineate the major risk factors for developing postoperative anxiety and the classic therapeutic modalities used to reduce symptoms and treat the psychological manifestations of anxiety.

General anesthesia and surgery are associated with changes in the shape of the chest that result in atelectasis, a major factor in the development of postoperative respiratory failure. Postoperative noninvasive positive pressure ventilation (NIPPV) has been shown to improve oxygenation and ventilation for high-risk patients. NIPPV has been used as rescue therapy for patients developing acute respiratory distress postoperatively, and appears to be most frequently successful in patients whose problem is atelectasis or obesity. Failure to respond to NIPPV after 20 minutes is usually an indication of intubation, mechanical ventilation, and transfer to the intensive care unit.

Spinal and epidural anesthesia and analgesia, and the combination of the two techniques, have been excellent choices for the management of certain surgical procedures and continue to grow in popularity. The demand for increased patient mobility and quicker discharge for both inpatients and outpatients lends itself to the benefits of regional anesthesia. A neuraxial block is indicated for any surgical procedure in which the appropriate sensory level can be accomplished without any adverse outcome. This article outlines the indications and contraindications for these techniques.
