BERMUDEZ-GUERRERO, Francisco José et al. A comparative analysis of 3 sedation guidelines for patients undergoing subarachnoid anesthesia. Randomized, single blind clinical trial. Rev. colomb. anestesiol. [online]. 2015, vol.43, n.2, pp.122-128. ISSN 0120-3347.

Introduction: Sedation is defined as the set of actions aimed at having a quiet, comfortable, pain-free patient during a diagnostic or therapeutic procedure without any bad memories. Since the standard regional anesthesia techniques used in clinical practice are relatively traumatic and painful procedures, sedation has been introduced to make these interventions more comfortable for the patient and to facilitate the patient's cooperation. Objective: To establish the efficacy of three sedation guidelines in patients undergoing sub-arachnoid anesthesia. Methodology: Experimental, randomized, prospective, single blind clinical trial comparing three guidelines for the sedation of patients undergoing subarachnoid anesthesia. Results: All of the patients in the trial received anxiolysis, collaborated with the puncture and said that they would not be afraid to receive subarachnoid anesthesia in the future. There were no complications including respiratory depression, nausea, vomiting or any other complications reported with the use of the sedation guidelines. Patient satisfaction was high. Withdrawal reflex (P = 0.0003) and puncture related pain (P = 0.0069) were more common in the group using the intravenous midazolam-only guideline and patient satisfaction with sedation was also lower in this group; however, the three guidelines showed good efficacy. Conclusions: The three sedation guidelines presented were effectively used in subarachnoid anesthesia; the results were more favorable with the use of midazolam + fentanyl or midazolam + ketamine.
