BACKGROUND Recurrent nocturnal hypoxemia in obstructive sleep apnea enhances sympathetic function, decreases baroreceptor sensitivity, and weakens peripheral vascular responses to adrenergic signals. The authors hypothesized that the percentage of total sleep time spent at oxyhemoglobin saturation (SaO2) less than 90% and minimum nocturnal SaO2 on preoperative polysomnography are associated wit...
Intraoperative management of hypoxemia with recruitment maneuvers: are the benefits worth the costs?
تنفس یکی از اساسی ترین نیازهای انسان است که در صورت عدم تأمین این نیاز، حیات انسان چند دقیقه ای بیشتر ادامه نخواهد یافت. اهمیت این فعالیت حیاتی از تأثیر آن بر تغذیه سلولها به عنوان کوچکترین واحد سازنده بدن انسان نشأت می گیرد، زیرا اکسیژن یکی از مواد ضروری برای سلولها می باشد و کسب این ماده حیاتی فقط از طریق تنفس مناسب و راحت امکان پذیر است .
Background It is speculated that opioid-free anesthesia may provide adequate pain control while reducing postoperative opioid consumption. However, there currently no evidence to support the speculation. The authors hypothesized balanced anesthetic with dexmedetomidine reduces opioid-related adverse events compared remifentanil. Methods Patients were randomized receive a standard either intraop...
BACKGROUND AND OBJECTIVES Perioperative hypoxemia is common in cardiac surgeries, and atelectasis is the main cause. Besides, we can mention extracorporeal circulation (ECC), dissection of internal thoracic arteries, and previous clinical status of the patient among others as its causes. The present study elaborated an anonymous questionnaire to observe ventilatory strategies for hypoxemia in c...
PURPOSE To highlight technical aspects and pitfalls of spinal anesthesia (SA) in infants. METHODS The medical history and perioperative course of all infants who underwent SA over a 28-month period were collected (retrospectively in the first 20). RESULTS Sixty-two infants underwent surgery under SA. Fifty-five were premature and former-premature, postconceptional age 43.3 +/- 5.0 weeks, we...
Anesthesia and surgery are associated with significantly increased morbidity and mortality in patients with pulmonary hypertension due mainly to right ventricular failure, arrhythmias, postoperative hypoxemia, and myocardial ischemia. Preoperative risk assessment and successful management of patients with pulmonary hypertension undergoing cardiac surgery involve an understanding of the pathophy...
The perioperative use and relevance of protective ventilation in surgical patients is being increasingly recognized. Obesity poses particular challenges to adequate mechanical ventilation in addition to surgical constraints, primarily by restricted lung mechanics due to excessive adiposity, frequent respiratory comorbidities (i.e. sleep apnea, asthma), and concerns of postoperative respiratory ...
