The Sedation Anesthesia for Prolotherapy and Intramuscular Stimulation / 대한통증학회지

ABSTRACT

BACKGROUND: Painful experiences during procedures such as prolotherapy and intramuscular stimulation are stressful to patients and can affect the treatment outcome. We present a method for relieving pain and increasing the level of patient comfort during the procedure. METHODS: Twenty six patients who requested sedation anesthesia during the procedure were examined. All patients were injected with 500 ml of 0.9% normal saline and were monitored by electrocardiography, blood pressure and pulse oximetry. The patients were supplied with oxygen (3 L/min) through a nasal cannula. Midazolam (0.02 mg/kg) and alfentanil (8 microgram/kg) was injected before the procedure and a bolus injection was administered during the procedure if patients felt any pain. The duration of the procedure, the total amount of drugs, the changes in the systolic blood pressure, heart rate, pulse oxygen saturation, sedation and pain level during procedure, satisfaction scale after the procedure, complications and the incidence of amnesia were evaluated. RESULTS: Twenty one patients had a moderate level of sedation, 15 patients did not feel any pain during the procedure, 17 patients had high level of satisfaction (8-10). No patient experienced complications after the procedure, or unstable vital signs, and 6 patients could not remember the procedure. CONCLUSIONS: Sedation anesthesia is a safe method for relieving pain during the procedure, and most patients had a high level of satisfaction.
