Randomized Controlled Trial Comparative Study
Labor epidural anesthetics comparing loss of resistance with air versus saline: does the choice matter?
This study examined whether air or saline, used for the loss-of-resistance (LOR) technique, resulted in a difference in pain relief or adverse events for laboring parturients. Previous studies had mixed findings regarding the onset of analgesia and subsequent pain relief. Research questions were as follows: Is there difference in analgesic onset for patients receiving air vs saline during the LOR technique? Do women receiving the air method for LOR experience any difference in the quality of pain relief from that of women receiving saline? Is there any difference in the incidence of analgesic distribution or segmental pain relief in women receiving the air vs the saline method? Is there any difference in the incidence of adverse effects in women receiving air vs saline during the LOR technique? This was an experimental, prospective study with 50 women. ⋯ A dermatome level recorded the spread of analgesia. No significant differences were found between groups for onset or quality of analgesia. There was a significant increase in the number of subjects who experienced segmental blocks after receiving air during the LOR technique.

This case study describes a 51-year-old, ASA physical status II Hispanic man who underwent liposuction to the anterior neck and resection of adipose tissue of the posterior neck. The patient was diagnosed with multiple symmetric lipomatosis, better known by its eponym, Madelung disease. This disease is characterized by abnormal adipose tissue growth primarily in the neck and shoulder regions. ⋯ In addition, flexion and extension of the neck was limited by a minimum of 20 degrees because of the pathology. The patient was deemed as having a difficult airway, and an awake fiberoptic intubation was planned and used successfully. The subsequent surgical procedure progressed without incident, and the patient was transferred to a stepdown unit for monitoring of his airway postoperatively.
