简要总结
Operating table height influences operator comfort and performance during neuraxial anaesthesia, particularly when the patient is positioned sitting. This study aimed to analyse the effect of operating table height on the success rate and incidence of complications during spinal anesthesia, particularly done by trainees/residents.
详细描述
Patients who met the inclusion criteria and did not meet any exclusion criteria were randomised by computer software into two groups according to operating table height - set with puncture site at the level of the operator's umbilicus or the operator's xiphoid process - with group allocation concealed in opaque envelopes. Operators were enrolled by consecutive sampling, consisting of anaesthesiology residents who met the eligibility criteria and were present in the operating theatre during the study period. The outcomes assessed included subarachnoid block success, procedural duration from needle insertion to free flow of cerebrospinal fluid, the need for needle redirection, the need for needle reinsertion, operator comfort, operator posture analysis, and minor complications such as paresthesia or vascular puncture
