BackgroundIntra-operative pain during Caesarean delivery (PDCD) is the leading cause of successful litigation against obstetric anaesthesiologists. PDCD may require conversion to general anaesthesia (GA). The aim of this analysis is to assess our incidence of PDCD and associated GA conversion.MethodsData were collected from electronic patient records. Data included baseline demographics, incidence of PDCD and rates of GA conversion, proportion of PDCD cases attributable to failed epidural (EA) or spinal anaesthesia (SA), and level of sensory and motor blockade in cases of PDCD. Results were audited against current standards set by the Royal College of Anaesthetists 'rates of PDCD should be <5% for category 4, <15% for categories 2-3, and <20 % for category 1 CD ' and that 'rates of conversion to GA due to neuraxial complications should be <1% for category 4, <5% for categories 2-3 and <15% for category 1 patients'.ResultsDuring the 12-month study period, 2,429 patients underwent CD, of whom 52 (2.1%) experienced PDCD. The incidence of PDCD was 3.1% (41/1,309) for category 1-3 patients, while 1% (11/1,120) of category 4 patients experienced PDS. Of the 52 patients with PDCD, 17 patients required GA (33%). SA was used in 24/52 (47%) cases and EA in 28/52 (53%) cases. The median level of sensory block in patients with PDCD was located at the T4 dermatome, the median level of motor block was Bromage level 2.ConclusionsPDCD occurred in 2.1% of CD, one-third required conversion to GA. Most patients experiencing PDCD met current motor and sensory blockade criteria.Copyright © 2024 Elsevier Ltd. All rights reserved.
