Previous studies have found excessive cuff pressures in simulated patients intubated by North American emergency physicians as well as patients intubated in the prehospital setting and emergency department (ED). This study assessed whether patients intubated in a UK prehospital setting or ED had excessive cuff pressures.Method Prospective observational study in five ED in southwest England over a 2-month period. All patients over 18 years and intubated in the prehospital setting or in the ED were included. Clinical staff independent of the patients' care recorded the following: age, sex, presenting complaint and indication for intubation, tube size and cuff pressure. Neither the paramedics nor the participating ED staff were aware of the study purpose. Cuff pressure measurements were recorded using a standardised cuff inflator pressure gauge.Result 61 patients were recruited. The median and mean cuff pressures were 58 and 62 cm of water, respectively. 75% of patients had a cuff pressure greater than 30 cm of water. The median cuff pressures in those patients intubated by senior emergency physicians, junior emergency physicians and paramedics were 70, 46 and 79 cm of water, respectively.Conclusion Excessive tracheal tube cuff pressures were demonstrated in the majority of patients intubated both in the prehospital setting and ED. This is in keeping with existing evidence. Early measurement and adjustment of cuff pressures is recommended for those patients who require ongoing care.
