Background: Sore throat is not an uncommon complaint following general anaesthesia (GA) with endotracheal intubation. It has been a source of considerable discomfort particularly in those patients who had thyroid surgery. Driven by the increased number of patients with post-intubation sore throat following thyroid surgery, the aim of the present study was to evaluate the contributing factors of sore throat in patients who had thyroid surgery under general anaesthesia.
Methods: A total of 57 consecutive patients who had thyroid surgery from November 1998 to April 1999 was included in this prospective study. Factors such as intubation time, number of intubation attempts, size and type of endotracheal tube (ETT) used, gender and age were recorded. The nature and extent of the surgical procedures were also studied. Postoperative symptoms were assessed by questionnaire on the day after surgery and the different parameters were compared and analysed.
Results: The incidence of post-intubation sore throat following thyroid surgery was documented in 39 (68.4%) patients. Twenty-seven (47.4%) patients had a mild complaint of sore throat, which resolved after the third day. The data from the present study show that the size of ETT and extent of surgical procedure were significant contributing factors affecting the postoperative recovery.
Conclusion: The outcome of the present study demonstrated a substantial increased incidence of sore throat after thyroid surgery under GA. Postoperative sore throat following thyroid surgery under GA may be caused by multiple contributing factors. Nonetheless effort and care should be taken during endotracheal intubation and surgery to reduce this unpleasant complaint arising mainly from pharyngeal irritation or trauma.

Effectiveness of amylmetacresol and 2,4-dichlorobenzyl alcohol throat lozenges in patients with acute sore throat due to upper respiratory tract infection: a systematic review protocol

REVIEW QUESTION/OBJECTIVE: This review aims to determine the best available evidence related to the effectiveness of amylmetacresol and 2,4-dichlorobenzyl alcohol throat lozenges in patients with acute sore throat due to upper respiratory tract infection (URTI). The objective is to examine the analgesic properties of amylmetacresol and 2,4-dichlorobenzyl alcohol (AMC/DCBA) throat lozenge comparing with placebo for the relief of pain in patients with acute sore throat due to URTIs.The review question is:More specifically, the objectives are to.

Fulltext Clinical performance of the LMA Protector™ airway in moderately obese patients

BACKGROUND: The 4th National Audit Project of The Royal College of Anaesthetists and The Difficult Airway Society (NAP4) reported a higher incidence of supraglottic airway device (SAD) related pulmonary aspiration in obese patients especially with the first-generation SADs. The latest single-use SAD, the Protector™ provides a functional separation of the respiratory and digestive tracts and its laryngeal cuff with two ports allowing additional suction in tandem with the insertion of a gastric tube. The laryngeal cuff of LMA Protector™ allows a large catchment reservoir in the event of gastric content aspiration.
METHODS: We evaluated the performance characteristics of the LMA Protector™ in 30 unparalysed, moderately obese patients. First attempt insertion rate, time for insertion, oropharyngeal leak pressure (OLP), and incidence of complications were recorded.
RESULTS: We found high first and second attempt insertion rates of 28(93%) and 1(33%) respectively, with one failed attempt where no capnography trace could be detected, presumably from a downfolded device tip. The LMA Protector™ was inserted rapidly in 21.0(4.0) seconds and demonstrated high OLP of 31.8(5.4) cmH2O. Fibreoptic assessment showed a clear view of vocal cords in 93%. The incidence of blood staining on removal of device was 48%, postoperative sore throat 27%, dysphagia 10% and dysphonia 20% (all self-limiting, resolving a few hours postoperatively).
CONCLUSIONS: We conclude that the LMA Protector™ was associated with easy, expedient first attempt insertion success, demonstrating high oropharyngeal pressures and good anatomical position in the moderately obese population, with relatively low postoperative airway morbidity.
