Objective: The Enhanced Recovery after Surgery Cardiac Society recommends using multimodal analgesia (MMA) for postoperative pain however, evidence-based guidelines have yet to be established. This study examines the impact of a standardized postoperative MMA pathway in reducing opioid consumption and related complications after cardiothoracic surgery (CTS). Methods: Within a multicenter healthcare system, a postoperative MMA pathway was developed and implemented at two CTS intensive care units (ICU) while the other CTS ICU opted to maintain the existing opioid-based pathway. A retrospective chart review was conducted on patients admitted to a CTS ICU within this healthcare system after conventional coronary artery bypass grafting and/or valve surgery from September 1, 2018, to June 30, 2019. Comparative analysis was conducted on patients prescribed MMA versus those managed with an opioid-based pathway. The primary outcome was total opioid consumption, converted to morphine milligram equivalents, 72-h post-surgery. Secondary outcomes included mobility within one-day post-surgery, ICU length of stay (LOS), time to first bowel movement (BM), and time to first zero Richmond Agitation-Sedation Scale (RASS). Results: Seven hundred sixty-two adults were included for final analysis. The MMA group had a higher body mass index, higher percentage of females, were more likely classified as African American and had higher scores for risk-adjusted complications. General Linear Model analysis revealed higher opioid consumption in the MMA group (Est. 0.22, p < 0.0009); however, this was not statistically significant after adjusting for differences in fentanyl usage. The MMA group was more likely to have mobility within one-day post-surgery (OR 0.44, p < 0.0001), have longer time to first BM (OR 1.93, p = 0.0011), and longer time to first zero RASS (OR 1.62, p = 0.0071). The analgesia groups were not a predictor for ICU LOS. Conclusions: Opioid consumption was not reduced secondary to this postoperative MMA pathway. The MMA group was more likely to have mobility within one-day post-surgery. Patients in the MMA group were also more likely to have prolonged time to first BM and first zero RASS. Development and evaluation of a perioperative MMA pathway should be considered. [ABSTRACT FROM AUTHOR]

Objective. We aim to study the impact of preoperative opioid dosage on postoperative length of stay (LOS) in patients undergoing thoracic spinal cord stimulator (SCS) placement surgery as a primary objective. Secondary objectives of this study include investigating patient-controlled analgesia (PCA) usage and postoperative complications like fever in relation to patients' preoperative opioid dosage and postoperative LOS. Methods. A total of 47 patients who underwent thoracic SCS for first time were retrospectively studied through chart review. These patients were categorized into two groups, with Group I patients taking a morphine equivalent dose (MED) of less than 100mg and Group II patients taking an MED of more than 100mg preoperatively. Results. Group I had 22 patients, and Group II had 25 patients. The average age in Group I was 53.45 years, and the average age in Group II was 50.16 years. There were seven males (38%) and 15 females (62%) in Group I, and in Group II there were 11 males (44%) and 14 females (56%). The average LOS in both groups was two days. In Group I, there were 16 patients (73%) who had an LOS of one day and six patients (27%) who had an LOS of more than one day, and in Group II there were 11 patients (44%) who had an LOS of less than one day and 14 patients (56%) who had an LOS of more than one day, with a P value of 0.047. On univariate analysis, postoperative fever and PCA usage correlated with longer hospital stay, with a P value of < 0.001. Conclusion. Patients on high-dose chronic opioid therapy, defined as an MED greater than 100 mg, who undergo thoracic spinal cord stimulator surgery tend to have longer postoperative hospital stays compared with patients on lower-dose opioid therapy.
