Patients undergoing head and neck surgery often have significant pain because of the anatomic area involved, the nature of the surgery and trauma associated with the anesthesia and surgery, or the use of packing postoperatively. A patient-controlled analgesia (PCA) infuser is available that allows the patient to direct delivery of their own analgesia. The physician orders the narcotic analgesic dose to be given, the interval between doses, and the total amount of analgesic to be delivered over 4 hours. ⋯ This system allows the patients to initiate intravenous delivery of their narcotic analgesic, and maintain control of pain, using small incremental doses of the analgesic agent. This PCA pump has been used successfully in a number of patients undergoing various general, head and neck, and facial aesthetic procedures. The general concept of the PCA pump, guidelines for use, and contraindications are presented.

Clinical Trial Controlled Clinical TrialTreatment of radiation- and chemotherapy-induced stomatitis.
Severe stomatitis is a common problem encountered during either radiation therapy or chemotherapy. Most therapeutic regimens are empirical, with no scientific basis. The purpose of this study is to determine the efficacy of various topical solutions in the treatment of radiation- or chemotherapy-induced stomatitis. ⋯ Degree of pain relief, duration of relief, side effects, and palatability were evaluated. The results showed that Dyclone provided the most pain relief. Dyclone and viscous lidocaine with 1% cocaine provided the longest pain relief, which averaged 50 minutes This study provides objective data and defines useful guidelines for treatment of stomatitis.

The purpose of this study is twofold. First, to introduce a new phenomenon--abductor vocal cord spasm, or abductor laryngospasm. Second, to reconcile a longstanding discrepancy involving the effect of lung inflation on vocal cord position. ⋯ Adductor laryngospasm was characterized by steady apposition of the vocal cords, massive laryngeal adductor muscle EMG activity, and silent PCA EMG activity. Abductor laryngospasm appears to be the physiologic converse of adductor laryngospasm. The results of this study show that lung inflation can produce either vocal cord abduction or adduction, depending on whether the dog is hypoventilated or hyperventilated before administration of CPAP.
