Objectives: To know, through an online survey, the usual clinical practice of Chilean anesthesiologists regarding central venous catheterization in patients undergoing elective neurosurgery. Material and Methods: An email was sent with a link to a questionnaire to anesthesiologists belonging to the Society of Anesthesiology of Chile (SACH). The questionnaire consisted of an anonymous questionnaire, with multiple-choice questions that included data referring to experience as an anesthesiologist, experience in neuroanesthesia, indication of central venous access in elective neurosurgery, access of choice, technique used, and immediate and late complications. results: A valid response was received to the online survey by 180 anesthesiologists, which represents a response rate of 50%. Only 14.4% of the respondents were classified as specialists in neuroanesthesia. The majority acces corresponded to the Internal Jugular. The main indication was the use of vasoactive drugs in 92.18%. Regarding clinical scenarios, 95.4% of respondents used a central venous route in posterior fossa surgery, while only 9.41% used it in minimally invasive surgery. 69.3% of the respondents indicated that they had presented an immediate complication related to the procedure, with arterial puncture being the most frequent with 72.1%. Protocols for perioperative management only existed in 17.8% of cases. There are no significant differences in the usual clinical practice among specialists in neuroanesthesia and general anesthesiologists in most of the items analyzed. Conclusions: From the data obtained, we observed that there is no uniform criterion in the indication, access and control of the central venous catheter in the context of elective neurosurgery. The foregoing could be explained by the scarce protocolization of anesthetic management in these surgeries. It is of interest to verify that there are no differences in clinical practice among anesthesiologists specialized in this area and those unusual in neurosurgical procedures.
