The effect of pilot balloon design on estimation of safe tracheal tube cuff pressure

ANAESTHESIA, Issue 8 2010
K. M. Janossy
Summary We studied the effect of pilot balloon design on the ability of experienced anaesthetists to assess and inflate tracheal tube cuffs to safe pressures. A model trachea was designed, incorporating a degree of compliance and an air leak, to evaluate six different pilot balloons grafted onto identical tracheal tubes. Pilot balloons were inflated to one of four pressures and anaesthetists were asked to estimate whether the pressure was acceptable, too low or too high. Anaesthetists were then asked to inflate the cuff of each tube. Overall, 103 (42.9%) of anaesthetists' assessments of tracheal tube cuff pressures were correct (33% correct would be expected by chance, p = 0.002). Pressures generated by anaesthetists inflating tracheal tube cuffs were very variable. Median (IQR [range]) pressures for each pilot balloon ranged from 29 (17,43 [9,56]) cmH2O to 74 (49,114 [4,140]) cmH2O (p < 0.001). The design of the pilot balloon significantly affects anaesthetists' ability to inflate tracheal tube cuffs to safe pressures. [source]

Simple, reliable replacement of pilot balloons for a variety of clinical situations

PEDIATRIC ANESTHESIA, Issue 6 2010

Summary When a pilot balloon fails or is an impediment to an intubation, such as via a pediatric laryngeal mask, options are generally limited to a tracheal tube exchange. Simple and effective solutions are described to replace a pilot balloon in a variety of clinical situations by using equipment that is readily available in operating rooms. Equipment such as intravenous catheters or epidural clamp connectors provides reliable, light weight, and streamlined substitutions for pilot balloons when connected to the pilot-cuff inflation line.
