“…Stethoscopes have been used to detect leaks around uncuffed tracheal tubes in children [30] and in animal studies [31]. Stethoscopes have also been used as a leak detector in a tracheal tube pressure relief valve system [27], and have been investigated as a tool to detect successful tracheal intubation [32, 33]. To our knowledge, the use of stethoscopes to guide tracheal tube cuff inflation to optimal pressures has not been studied.…”

SummaryTracheal tube cuffs are commonly inflated to pressures exceeding the recommended upper limit of 30 cmH 2 O. We evaluated whether a stethoscope-guided method of cuff inflation results in pressures within the recommended range. Patients were randomly assigned to receive one of two methods of cuff inflation. In the standard 'just seal' group, air was introduced into the tracheal cuff until the audible leak at the mouth disappeared. In the stethoscope-guided group, air was introduced into the cuff until a change from harsh to soft breath sounds occurred, whilst listening with a stethoscope bell placed over the thyroid cartilage. Twenty-five patients were recruited to each group. The median (IQR [range]) cuff pressure in the 'just seal' group was 34 (28-40 [18-49]) cmH 2 O, and in the stethoscope-guided group was 20 (20-26 [16-28]) cmH 2 O, p < 0.0001. The stethoscope-guided method of tracheal tube cuff inflation is a novel, simple technique that reliably results in acceptable tracheal cuff pressures.

“…Previous studies have found a difference in the incidence of the sore throat between men and women. 15,16 Similarly, some studies have shown that the incidence of post operative sore throat was higher in the age group of 18-30 years (18.3%) and 30-40 years (26.2%), but it was <5% in patients aged >50 years. 17 In a study by Rahmani et al, 18 they compared the pilot balloon palpatory method with a fixed volume of 10 ml for inflating the cuff, and the result demonstrated a cuff pressure of 118.15 ± 22.15 cmH2O and 44.96 ± 21.77 cmH2O respectively.…”

Objective: To compare the efficacy of “Just seal” method of endotracheal tube cuff inflation versus “stethoscope guided”method for reduction of frequency of post operative sore throat. Study Design: Prospective observation study. Place and Duration of study: This study was conducted in Main operation theatre, CMH Kohat from 1st September 2018 to 30th November 2018. Patients and methods: 44 patients divided in two groups of 22 each were made, Group JS and Group SG. Inj Propofol and atracurium was used for induction of general anaesthesia, and Inj Nalbuphine was used as analgesic. Endotracheal intubation with 7.5 internal diameter ETT, was done after 3 minutes of injecting atracurium. In group JS, ETT cuff was inflated gradually till no leakage was heard. In group SG, ETT cuff was inflated slowly and stethoscope bell was placed over thyroid lamina till harsh sounds stopped. Age, volume used to inflate cuff, cuff pressure generated and complain of sore throat 02 hours after extubation were noted. Results: Mean age was 30.22 ±4.7 years and 30.13± 4.2 years for Group JS and SG respectively (p=0.946). Mean volume used was 6.81±0.41 ml and 4.95±0.29 ml for Group JS and SG respectively (p=0.000). Mean pressure generated was 34.90±4.48 cmH2O and 28.91±2.37 cmH2O (p=0.000). Frequency of Post operative sore throat was 54.55% (12/22) in JS group and 18.18 % (4/22) in SG group (p= 0.012). Conclusion: Stethoscope guided technique for inflation of ETT cuff is more effective in reducing frequency of post operative sore throat.

“…Several tests and observations have been proposed for the diagnosis of oesophageal intubation, all of which have limitations and varying degrees of reliability [5–7]. These include the absence of carbon dioxide in the expired gas on capnograph, the oesophageal detector device and, historically, sonomatic confirmation of tracheal intubation (SCOTI) [8].…”

Summary Accidental oesophageal intubation is still an important cause of anaesthetic morbidity and mortality. This study investigated the use of impedance respirometry to determine the position of a tracheal tube. Seventy‐nine patients undergoing general anaesthesia requiring tracheal intubation with muscle relaxation were recruited to the study. After pre‐oxygenation, tracheal tubes were placed in both the oesophagus and trachea; a breathing system was attached to one tube chosen randomly. A blinded observer was required to correctly identify the position of the tube within six tidal ventilations. The position of every tube connected to the breathing system was correctly identified. The median time to correctly identify tracheal and oesophageal tubes was 3 and 5 s, respectively. The median number of breaths to identify tracheal and oesophageal tubes was two for both groups. Every tube position was identified within the required six breaths. Impedance respirometry is a reliable method for diagnosing tracheal tube position.
