Postoperative nausea, vomiting, airway morbidity, and analgesic requirements are lower for the ProSeal laryngeal mask airway than the tracheal tube in females undergoing breast and gynaecological surgery
Abstract:The ProSeal LMA reduced the absolute risk of postoperative nausea and vomiting by 40% (53-13%). In patients without the need for morphine, the ProSeal LMA reduced the absolute risk of postoperative nausea and vomiting by 23% (37-14%). We conclude that the frequency of postoperative nausea, vomiting, airway morbidity, and analgesic requirements is lower for the ProSeal LMA than the tracheal tube in females undergoing breast and gynaecological surgery.
“…Postoperative hoarseness, sore throat, impairment of swallowing, pain, nausea and vomiting, and coughing are reduced, post-anaesthesia recovery unit length of stay is shortened, and increases in intra-ocular pressure and derangements in cardiovascular and respiratory function are less likely [1][2][3][4][5][6][7][8][9][10][11]. Furthermore, the LMA can be useful in the management of the difficult airway when facemask ventilation is inadequate [12].…”
SummaryWe compared the risk of pulmonary aspiration in patients whose lungs were mechanically ventilated through a laryngeal mask airway (35 630 procedures) or tracheal tube (30 082 procedures). Three cases of pulmonary aspiration occurred with the laryngeal mask airway and seven with the tracheal tube. There were no deaths related to pulmonary aspiration. The incidence and outcome of pulmonary aspiration detected in this study were similar to those previously reported. The adjusted odds ratio (OR) for pulmonary aspiration with the laryngeal mask airway was 1.06 (95% CI 0.20-5.62). Unplanned surgery (OR 30.5,) and male sex (OR 8.6, 95% CI 1.1-68) were associated with an increased risk of aspiration and age < 14 years with a reduced risk (OR 0.21, 95% CI 0.07-0.64). There were contraindications and exclusions to the use of the laryngeal mask airway but in this selected population the use of an laryngeal mask airway was not associated with an increased risk of pulmonary aspiration compared with a tracheal tube.

“…Peak airway pressure was 16 (SD 3 [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]) cmH 2 O. Airway seal pressure was 34 (SD 4 [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]) cmH 2 O. There were no important changes in measures of ventilation or oxygenation during the procedure.…”
SummaryThe ProSeal laryngeal mask airway (PLMA) has been used routinely for anaesthesia and for difficult airway management including airway rescue in non-fasted patients. Compared with the classic laryngeal mask airway the PLMA increases protection against gastric inflation and pulmonary aspiration, by separating the respiratory and gastro-intestinal tracts. The PLMA has potential advantages over use of the tracheal tube including smoother recovery, reduced pharyngolaryngeal morbidity and even reduced postoperative pain. We report a series of patients scheduled for emergency appendicectomy, without other risk factors for regurgitation, managed with the PLMA. Anaesthesia was induced and maintained with remifentanil, target controlled propofol and rocuronium. A series of 102 cases were managed without complications and high rates of first time placement of the PLMA (inserted over a suction tube placed in the oesophagus). With careful patient selection the PLMA may offer an alternative airway for use by experienced anaesthetists in patients undergoing minor lower abdominal surgery.
“…24,25) The incidence of postoperative sore throat is less in patients receiving the LMA (The Laryngeal Mask Co., Ltd., Seychelles). 26) SGAs also have some advantages when using in outpatient anesthesia. The patients with SGAs can tolerate lighter levels of anesthesia than ETs and typically do not require neuromuscular blockade and side effects of the medication or its antagonists.…”
