Pdf Summary

A study published in the AANA Journal explored the use of buffered lidocaine as an endotracheal tube (ETT) cuff medium in postoperative cardiac surgery patients. The study aimed to reduce pain and discomfort associated with ETT, decrease sedation requirements, and alleviate emergence phenomena (EP). Results from the pilot study showed a trend towards decreased coughing and pharyngitis, reduced propofol requirement, and no difference in adverse events between the intervention (lidocaine) and control (air) groups. The study highlighted the feasibility and potential efficacy of buffered lidocaine in improving patient outcomes postoperatively. Previous research has shown that lidocaine can reduce EP and sedative requirements in mechanically ventilated patients. While this pilot study did not reach statistical significance, it suggests the need for larger studies to confirm the benefits of using buffered lidocaine as an ETT cuff medium. The study is unique in its focus on cardiac surgery patients and its thorough analysis of sedative requirements and emergence phenomena, filling a gap in current evidence. Limitations of the study included a small sample size and variations in anesthetic and analgesic medications used. The authors emphasized the need for further research to validate the findings and explore the safety and efficacy of buffered lidocaine in a larger patient population.
