Pressure controlled versus volume controlled ventilation with laryngeal mask airway

Ventilation of nonparalyzed patients under anesthesia with laryngeal mask airway, comparison of three modes of ventilation: Volume controlled ventilation, pressure controlled ventilation, and pressure controlled ventilation-volume guarantee

“…Furthermore, the compliance was higher significantly in the PCV mode than that of VCV. Similar results were reported by Natalini et al .,[12] he concluded a decrease in the work of breathing with PCV demonstrated by the increase in PIP and the decrease in compliance in VCV mode as compared to PCV.…”

“…Stated advantages with respect to tracheal intubation include efficiency, the absence of need to use muscle relaxants and improved recovery profile. [56] Different modes of ventilation used with LMA in general anesthesia has been studied and compared,[71112] but no one had investigated the use of PC-VG.…”

“…[10] PCV advantage over volume controlled ventilation (VCV) is that the peak inspiratory pressure (PIP) in the former is reduced at the same tidal volume and inspiratory time. [1112]…”

New Developments in Anesthesia Ventilators

“…Small individual studies have observed that ventilation with pressure control mode results in better gas exchange during 1-lung ventilation 16 and effective positive pressure ventilation when a laryngeal mask airway is used. 17 If one extrapolates from the use of pressure control mode in the ICU, some additional uses can be considered intraoperatively. One use for pressure control mode is when increased resistance to gas flow through the ETT results in elevated airway pressures.…”

Supreme laryngeal mask airway for laparoscopic cholecystectomy in patient with severe pulmonary fibrosis

“…3 4 The laryngeal mask airway (LMA) seems to have advantages over the tracheal tube to reduce respiratory system resistance, 5 6 and the effectiveness of mechanical ventilation through LMA may be increased by the recourse to pressure-controlled ventilation. 7 Moreover, Proseal TM LMA (PLMA) resulted in smoother emergence from anaesthesia 8 and in lower frequency of postoperative nausea, vomiting, airway morbidity, and analgesic requirements than the tracheal tube. 9 SLMA is a new, single-use, latex-free, LMA TM with gastric access that combines the desirable features of the Fastrach TM , Proseal TM , and Unique TM LMA devices that may be easily inserted without placing fingers in the patient's mouth or that do not require an introducer tool for insertion and offers glottic seal pressures similar to the PLMA.…”
