RESUMO

OBJECTIVE: To demonstrate the characteristics, outcomes, and the circumstances associated with intraoperative recall of awareness. MATERIAL AND METHOD: Relevant data of intra-operative recall of awareness were extracted from the Thai Anesthesia Incident Monitoring study (Thai AIMS) database of 1996 incident reports and 2537 incidents which were conducted among 51 hospitals throughout Thailand from January to June, 2007. Details regarding patients, surgical, anesthetic and systematic factors were recorded in a structured data record form. The completed record forms were reviewed independently by three anesthesiologists. The descriptive statistic was analyzed by using SPSS software version 11.5 and demonstrated in number and percent. RESULTS: Twenty-one incidents (21/1996 = 1.05%) of intra-operative recall of awareness were reported. Awareness was predominantly found in females (76.2%) and with ASA physical status I (47.6%). Most of the patients recalled events during the maintenance period and reported sound (71.4%), pain (52.4%), feeling operated (38.1%), paralysis (33.3%), recognizing intubated (4.8%) and panic (4.8%). Anxiety (33.3%), temporary emotional stress (19%), and post traumatic stress (4.8%) were found during immediate outcome assessment but scarcely sustained on the hospital discharged date. The factors associated with the incidents were anesthetic related in the majority especially ineffective monitoring (100%), pre-medication abandonment (100%) and light anesthesia (71.5%). CONCLUSION: Intra-operative recall of awareness in the Thai AIMS was 1.05% of all incident reports. Most of the events were considered as anesthesia related. The suggested corrective strategies were quality assurance activity, effective monitoring and equipment maintenance.

RESUMO

BACKGROUND AND RATIONALE: Size of spinal needle may be a factor which influences the success rate of spinal anesthesia. OBJECTIVES: To compare learning curves of using 25G and 27G quincke spinal needle for spinal anesthesia. SETTING: Department of Anesthesiology, Faculty of Medicine, Chulalongkorn University and King Chulalongkorn Memorial Hospital. DESIGN: Prospective randomized control trial. MATERIAL AND METHOD: Ten new first year anesthesia residents were randomized to 2 groups: Group I (n = 5) used 25G Quincke spinal needle, Group II (n = 5) used 27G Quincke spinal needle to perform 200 consecutive cases of spinal anesthesia. Number of success and failure was recorded by each individual resident anonymously. The learning curves of plotted by cumulative sum of success rate revealed an initial rapid improvement of success during the first 20 cases in both groups. The overall success rate of group I was 84% (95CI, 66.5-100) and group II was 87% (95%CI, 61.5-100); p = 0.89. The widest difference between the 2 learning curves at 20 attempts intervals was at the twentieth attempts with a success rate of 76.0% VS 65.0% in group I and group II respectively; p = 0.54. CONCLUSION: The learning curves of spinal anesthesia using 25G and 27G Quincke spinal needle showed rapid improvement of success rate at the first 20 spinal block and high overall success rate with no significant difference between the groups.
