Objectives
Erector spinae plane (ESP) blocks are a regional anaesthetic technique used for pain relief in thoracic procedures. Our centre has recently begun using ESP blocks pre-medical thoracoscopy for analgesia.
Methods
Nine patients undergoing MT from September 2021 to February 2022 were included. Opioid use and depth of required sedation was recorded. Pre and post pain scores and at home were recorded by interview and review of charts. A functional pain questionnaire was administered via telephone.
Results
Average greatest depth of sedation using propofol was 1.92 (standard error of mean [SEM] 0.27), with remifentanil 2.52 (SEM 0.46). 78% required oral analgesia on day 0 post discharge. 55% required oral analgesia on post-op day 1. Patients used an average of 3.33 mg oral morphine (SEM 2.35) in hospital, and 3 mg (SEM 2) on post-op day 1. Periprocedural pain scores were 0.66 (SEM 0.27). Pain scores in recovery were 1.56 (SEM 0.76). Pain scores 3–12 h post discharge were 3.56 (SEM 0.7), while pain scores on post-op day 1 were significantly higher at 5.56 (SEM 0.90) (Figure 1). Functional pain scoring showed patients doing activities of daily living well with a good ability to breathe and cough. All felt that their pain was well controlled on the day of the procedure and at home. No complications were reported.
Conclusions
ESP blocks provide good analgesia. Pain scores showed significant analgesic effect lasting several hours. The project showed pain outcomes and patient acceptability were good for the use of regional anaesthesia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
