Anesthesia Clinical Trial
Official title:
Sevoflurane as an Anesthetic During Dilation and Evacuation Procedures: Does it Increase Blood Loss and Interventions for Blood Loss and Why Do Anesthesiologists Choose to Use It?
Sevoflurane is an FDA-approved anesthetic drug commonly used for anesthesia during second trimester abortion procedures. It has a few advantages, including ease of use by the anesthesia provider. However, the literature suggests that when used in doses higher than those used at Oregon Health & Science University (OHSU) and Lovejoy, it is associated with an increase in the risk of bleeding. The investigators study aims to test whether the lower dose used at OHSU and Lovejoy during second trimester abortion procedures causes any difference in blood loss, when compared to similar abortion procedures for which this drug is not used.
This study seeks to examine the bleeding complications associated with use of sevoflurane in general anesthesia regimens for second trimester abortion procedures and assess anesthesia providers' use and beliefs regarding possible risks associated with newer inhalational agents such as sevoflurane in this setting. Participants' anesthesia will either be intravenous (IV) propofol, IV midazolam, IV fentanyl and nitrous oxide or this same regimen combined with sevoflurane during maintenance of anesthesia. Procedural outcomes, specifically those related to bleeding complications, including need to intervene for excess blood loss, will be recorded and analyzed to establish if such a relationship between use of sevoflurane and excess blood loss exists. ;
