Survey on the practice of anaesthesiologists in inguinal hernia surgery in Galicia

Abstract

Objectives: To evaluate the preference in the anaesthetic technique by anaesthesiologists for the management of inguinal hernia surgery in Galicia.

Material and methods: Using the National Catalogue of Hospitals of the Ministry of Health and Consumer Affairs in Galicia, a questionnair was sent to the Heads of Anaesthesiology Service and Coordinators of the Postanaesthesia Care Unit (PACU) with 11 questions on the anaesthetic technique chosen by anaesthesiologists in the management of patients for inguinal hernia surgery, as well as their reasons.

Results: The questionnaire was sent to 11 hospitals: 8 with PACU and 3 District. A total of 94 professionals responded, 56% with more than 10 years of experience, who performed between 8-10 procedures/month (58%) on an outpatient basis (61.54%). The most used anaesthetic technique was intradural in 52.8%, compared to 41.8% of general anaesthesia. Respondents with more than 10 years of experience preferred spinal anaesthesia in 38.6% of cases, compared to those with less experience (6.8%) (P=.037). One in 4 of those who chose general anaesthesia used ultrasound-guided interfascial blocks (27.5%). The local anaesthetic most used in intradural anaesthesia was hyperbaric bupivacaine (70.8%) at doses higher than 7mg.

Conclusion: Intradural anaesthesia with hyperbaric bupivacaine was the technique most chosen by anaesthesiologists for the management of inguinal hernia surgery. The anaesthetic techniques chosen among the different hospitals did not follow a homogenous distribution. In this survey, there was a tendency to choose the technique associated with the experience of the anaesthesiologist.
