hip knee surgery obstructive sleep syndrome

A Gam, I Priel, D Hendel
Obstructive sleep apnea syndrome is defined as a condition of repeated episodes of apnea and hypopnea during sleep, accompanied by excessive daytime sleepiness. This syndrome is common among the adult population, and is related to an increased risk for significant complications, during and immediately after surgery. Often, this condition is undiagnosed, and is not considered in the pre-operative evaluation. Therefore, it is highly important to recognize this syndrome in patients who are scheduled for elective surgery, and provide appropriate management, in order to avoid life-threatening exacerbation in the perioperative period...

Sleep apnea syndrome (SAS) is a condition of repeated episodes of apnea and hypopnea during sleep. It can cause life-threatening morbidities, including cardiac arrhythmia and ischemia, hypertension, and respiratory arrest, and even death. In a retrospective study at our institution of patients who underwent hip or knee total joint arthroplasty (TJA) with a diagnosis of SAS, we hypothesized that avoiding factors that exacerbate SAS in the perioperative period would minimize adverse outcomes. There were 19 patients with a preoperative diagnosis of moderate or severe SAS; 15 patients received continuous positive airway pressure or bilevel positive airway pressure noninvasive ventilation, 1 patient experienced respiratory arrest secondary to intraoperative propafol, and 2 patients developed postoperative respiratory depression...

OBJECTIVE: To identify and assess the impact of postoperative complications in patients with unrecognized or known obstructive sleep apnea syndrome (OSAS) undergoing hip replacement or knee replacement compared with control patients undergoing similar operations. Although OSAS is a risk factor for perioperative morbidity, data quantifying the magnitude of the problem in patients undergoing non-upper airway operations are limited. PATIENTS AND METHODS: This retrospective, case-control study from a single academic medical institution included patients diagnosed as having OSAS between January 1995 and December 1998 and undergoing hip or knee replacement within 3 years before or anytime after their OSAS diagnosis...
