We thought that the rate of postoperative pulmonary complications might be higher after pressure-controlled ventilation than after volume-controlled ventilation. We analysed peri-operative data recorded for 109,360 adults, whose lungs were mechanically ventilated during surgery at three hospitals in Massachusetts, USA. We used multivariable regression and propensity score matching. Postoperativ...

STUDY OBJECTIVE To quantify the impact on peak airway pressure of pressure-controlled and volume-controlled ventilation during Laryngeal Mask Airway (LMA) use. DESIGN Prospective, crossover clinical study. SETTING University-affiliated hospital. PATIENTS 32 ASA physical status I and II patients undergoing general anesthesia with the LMA. INTERVENTIONS Patients were ventilated for three ...

BACKGROUND Either controlled ventilation or spontaneous respiration is commonly used in general anesthesia for inhaled foreign body removal via rigid bronchoscopy. Controversy in the literature exists concerning which form of ventilation is optimally suited for bronchoscopy. We performed a meta-analysis to compare controlled ventilation and spontaneous respiration with respect to complications,...

Obesity impairs peri-operative lung function. To evaluate the impact of pressure support ventilation vs pressure controlled ventilation in moderately obese adults upon early postoperative lung function, we randomly assigned 68 moderately obese patients (body mass index 25-35 kg x m(-2)) undergoing minor surgery to receive intra-operative ventilation either with pressure support or pressure cont...

Background Although both methods of spontaneous respiration and controlled ventilation during anesthesia are safe and effective for managing children with foreign body aspiration, there is no consensus from the literature as to which technique is optimal. This study aimed to determine the outcomes of anesthetic techniques in pediatric rigid bronchoscopy for foreign body removal. Materials and M...
