IntroductionEpidural analgesia is acknowledged as the most common method of analgesia during labor. If emergent Caesarean section (CS) is indicated in parturient with existing labor epidural, the need for conversion from epidural analgesia to regional (RA) or general anesthesia (GA) increases accordingly. Recent guidelines suggest the rate of conversion to general anesthesia shows the quality of obstetric anesthesia care and should be under 5%.The AimThe aim of this study is to determine the conversion rate from epidural analgesia to Caesarean section anesthesia in "Sveti Duh" University Hospital Zagreb in order to enhance the quality of anesthetic care for obstetric patients.MethodsWe retrospectively included in the study all parturients who received epidural labor analgesia but needed subsequent regional or general anesthesia for Caesarean section in our institution for the period of 1st January 2021 to 31st December 2021. After the data analysis on the conversion rate from epidural analgesia to Caesarean section anesthesia had been performed, we compared our data to current standards and relevant literature findings.ResultsAltogether 1202 epidural catheters were placed for labor analgesia in the study period, and in 199 of these cases, the emergent Caesarean section was indicated. Epidural analgesia was converted to epidural anesthesia (EA) in 153 (76,9%) parturients, to general anesthesia in 40 (20,1%), and to spinal anesthesia (SA) in six (3%) parturients. After comparison with recommended quality standards and with the results of similar studies by other authors, our findings show a significantly higher rate of conversion from epidural analgesia to general anesthesia than has been desirable since then.ConclusionIn order to reach the required quality standards regarding the conversion rate from epidural analgesia to Caesarean section anesthesia, it is necessary to improve the organization of the work of the obstetric anesthesiology team according to the principle of subspecialization. It is imperative to implement the best clinical practice protocols for obstetric anesthesiologists, but also to enhance the communication and coordination with the obstetric team.
