“…The peripharyngeal gas leakage and gastric insufflation were stopped by simple manipulation; therefore, further gastric insufflations did not occur. However, pulmonary aspiration of gastric contents remains a major concern when using SLA devices, 15,16 and this occurrence is considered more prevalent during laparoscopic surgery in gynecology patients. 17 We should be all the more attentive to perilaryngeal leaks, consequent gastric insufflations, and pulmonary aspiration when using an SLA fitted with a cuff.…”

Purpose The aim of this study was to compare the Streamlined Liner of the Pharynx Airway (SLIPA TM ) with the ProSeal Laryngeal Mask Airway (LMA-ProSeal TM ) in mechanically ventilated paralyzed patients undergoing laparoscopic gynecologic surgery. Methods One hundred and one patients were allocated randomly to SLIPA (n = 50) or to LMA-ProSeal (n = 51) treatment groups. After induction of general anesthesia and insertion of the assigned supralaryngeal airway (SLA) device, we made note of the occurrence of any gastric insufflation and perilaryngeal leakage. We then evaluated the anatomical fit of the SLA device using a fibreoptic bronchoscope, and we assessed the airway sealing pressure and respiratory mechanics with change in head position and during peritoneal insufflation. After surgery, we evaluated the severity of postoperative sore throat and the presence of blood or regurgitated fluid on the SLA device. Results The insertion success rate, gastric insufflation, perilaryngeal leakage, anatomical fit, airway sealing pressure, respiratory mechanics, severity of sore throat, and incidence of blood and regurgitated fluid on the device were similar between the two groups. The incidence of perilaryngeal leakage with changes in the patient's head position was lower with the SLIPA group than with the LMA-ProSeal group (3/50 vs 11/51, respectively; P = 0.026). During peritoneal insufflation, perilaryngeal leakage did not occur with the SLIPA but occurred in four cases with the LMA-ProSeal (P = 0.045). Conclusion Both the SLIPA and the LMA-ProSeal can be used effectively and without severe complications in paralyzed patients undergoing laparoscopic gynecological surgery. However, the SLIPA offers the advantage of less perilaryngeal gas leakage than the LMA-ProSeal with change in head position and during insufflation of the peritoneal cavity. This trial is registered with ANZCTR (ACTRN12609000914268).

“…We have no data on whether aspiration risk is higher when using an FT-LMA to place an ETT than when an ETT is placed using other methods. Keller et al 87 reported a case of aspiration associated with the elective use of the FT-LMA in a patient with an asymptomatic hiatal hernia. In their case, no exceptional events took place prior to the regurgitation episode, i.e., difficult insertion or an inability to ventilate with low peak pressure.…”

Purpose To provide an evidence-based overview and update on the use of the Fastrach TM Intubating Laryngeal Mask AirwayÒ (FT-LMA) when used within operative and non-operative settings. Principal findings The FT-LMA is available in three sizes to provide ventilation and the ability to pass an endotracheal tube (ETT) into the trachea blindly, semi-blindly, or with indirect visualization for patients over 30 kg. The Chandy maneuver is recommended routinely; the first maneuver optimizes ventilation, and the second maneuver increases success at endotracheal intubation (ETI). The manufacturer's reinforced tube or a pre-warmed or reversed standard ETT may be utilized. Insertion and ventilation are successful in almost all patients. Blind ETI is highly successful; adjuncts are generally not necessary. The FT-LMA has a proven role in the airway management of anticipated difficult operating room (OR) intubations, unanticipated OR intubations, cervical spine injuries, and limited airway access situations. Literature in the pre-hospital and emergency department settings is limited but favourable. The FT-LMA has compared favourably with fibreoptic intubation, the LMA-Classic TM , the laryngeal tube, and the CobraPLA TM . Initially, the more expensive LMA CTrach TM appeared to be more successful, but overall it is not. The FT-LMA airway seal pressures are excellent; serious complications are uncommon, and the FT-LMA figures prominently in most difficult airway guidelines. Conclusions The FT-LMA has proven to be a useful difficult airway device both within and outside of the operating room. Effective ventilation is established in nearly all cases, and blind ETI is possible in the vast majority of cases if the optimal techniques described are used. Serious complications are uncommon. Constatations principales Le FT-LMA est disponible en trois tailles pour permettre la ventilation et le passage d'une sonde endotrache´ale (SET) dans la trache´e de façon aveugle, semi-aveugle ou avec visualisation directe chez les patients pesant plus de 30 kg. La manoeuvre de Chandy est recommande´e de façon routinie`re; la premie`re manoeuvre optimise la ventilation, et la seconde augmente le succe`s lors d'une intubation endotrache´ale (IET). La sonde arme´e du fabricant ou une SET standard pre´chauffe´e ou inverse´e peut eˆtre utilise´e. L'insertion et la ventilation re´ussissent chez presque tous les patients. L'IET en aveugle a un taux de re´ussite e´leve´; en re`gle ge´ne´rale, les accessoires ne sont pas ne´cessaires. Le FT-LMA joue un rôle e´prouve´dans la prise en charge des voies ae´riennes lors d'intubations anticipe´es comme difficiles dans la salle d'ope´ration (SOP), d'intubations impre´vues en SOP, de le´sions de la colonne cervicale et dans les situations oul 'acce`s aux voies ae´riennes est limite´. La litte´rature portant sur son utilisation dans des contextes pre´-hospitaliers et dans le de´partement des urgences est restreinte mais favorable.

“…In spite of the low incidence of aspiration associated with the laryngeal mask [24], it should be used with caution in patients at increased risk of aspiration [25]. The practice of exchanging the laryngeal mask for a tracheal tube is a well recognised method of avoiding problems at extubation [23].…”

SummaryComplications at extubation remain an important risk factor in anaesthesia. A postal survey was conducted on extubation practice amongst consultant anaesthetists in the United Kingdom and Ireland. The use of short acting drugs encourages anaesthetists to extubate the trachea at lighter levels of anaesthesia. The results show that oxygen (100%) is not routinely administered either before extubation or en route to the recovery area. A trend towards a head up or sitting position at extubation is emerging. However, further research into the use of these positions is required. Airway related complications at extubation are relatively frequent but are usually dealt with by simple basic measures. The role of drugs such as propofol in decreasing the incidence of these complications needs further evaluation. Some of these results give concern for patient safety and for training. The importance of teaching and adherence to continued oxygenation until complete recovery is strongly emphasised. Nerve stimulators should be used continually as standard monitoring throughout the anaesthetic period when muscle-relaxing drugs are part of the anaesthetic technique. It has been shown that there are more adverse incidents associated with extubation than intubation and these are occurring not only during extubation itself, but also during the time spent in the recovery room [1][2][3][4][5]. The increased incidence of complications has been correlated with the pre-operative physical status, depth of anaesthesia at extubation, increasing age and gender with a male preponderance [2,6]. These complications remain consistent regardless of the type of operation [1].The problems associated with extubation may be broadly categorised into cardiovascular and respiratory complications. Cardiovascular complications include tachycardia, hypotensive and hypertensive episodes [7][8][9][10], which may be significant in patients with pre-existing ischaemic heart disease [11,12], pre-eclampsia [13] and in those undergoing neurological procedures [14]. Respiratory complications include local trauma, coughing, desaturation, breath-holding, masseter-spasm, laryngospasm, airway obstruction and aspiration [7,[15][16][17][18]].An on-line journal search revealed a lack of recent investigations or statistical data in these areas. This survey was performed with this in mind. The main aims of the survey were twofold. The first was to ascertain extubation practices with regard to the type of surgery, timing, position and techniques. The second was to estimate the incidence of problems associated with extubation and how these were treated. MethodsA postal survey was conducted in May 2004. A total of 845 Consultant Anaesthetists were randomly selected from the membership database of the Association of Anaesthetists of Great Britain and Ireland (AAGBI). These anaesthetists were sent the questionnaire, which they were asked to complete and return anonymously in the stamped, addressed envelope provided. The questionnaire (Fig. 1) was a structured document with...
