Case Reports
Airway management in a patient with a cleft palate after pharyngoplasty: a case report.
To describe a practical method of aiding nasotracheal intubation in a cleft palate patient with previous pharyngoplasty using a suction catheter under tactile guidance. Problems of airway management in these patients are also discussed. ⋯ Preoperative determination of the type of pharyngoplasty is essential to understand the anatomy of the patent velopharyngeal port. A history of pharyngeal flap infection, hyponasal voice or upper airway obstruction suggests possible port stenosis. We describe a tactile guided technique that is useful and practical. Use of a flexible suction catheter of small external diameter minimizes the potential for trauma, bleeding and creation of false passages.

To determine if the extent of sensory blockade after the intrathecal injection of hypobaric fentanyl (25 micro g) and bupicavaine (2.5 mg) in the sitting position in term parturients is influenced by body habitus. ⋯ Height did not influence the extent of sensory analgesia after initiation of intrathecal labour analgesia using a hypobaric solution injected with the parturient in the sitting position. Weight and BMI were associated with a non-clinically significant increase in the cephalic spread of analgesia, suggesting that dose adjustments based on body habitus in this population are not necessary.

Cumulative sum (cusum) analysis is a statistical and graphical tool that examines trends for sequential events over time. It has been used to determine proficiency in technical procedures. We used cusum to determine the number of labour epidural attempts necessary for proficiency in our training program. ⋯ After a period of training, residents are expected to perform the skill of labour epidural insertion independently. This study illustrates that some residents may need as many as 75 attempts to ensure proficiency. Training programs could use cusum to track the progress of their residents' technical skills in order to guarantee an adequate experience.
