Purpose: Single-port sleeve gastrectomy (SPSG) is increasingly performed in an ambulatory setting. Pain intensity when returning home remains a problem. The challenge is to be able to predict the evolution of postoperative pain (POP) at home by using parameters collected during the hospital stay. This study aimed to investigate whether immediate POP in the postanesthesia care unit (PACU) can predict pain intensity 24 h after surgery. Methods: Single-center retrospective study in patients with obesity who underwent ambulatory SPSG. POP and opiate requirements during PACU stay were registered. Patients were followed up at home during the first 4 postoperative days. The primary outcome was the correlation between opiate requirements in the PACU and Numerical Rating Scale (NRS) at home 24 h after surgery. Secondly, logistic regression was used to identify risk factors for moderate/intense pain 24 h after surgery. Results: Ninety-four patients were included during the study period. Twenty-two patients had NRS > 3/10 24 h after surgery. No correlation was found between the total dose of morphine in the PACU and pain intensity 24 h after surgery (r2 = − 0.07; P = 0.49). No predictive factor for moderate/intense pain 24 h after surgery was found. Conclusion: No correlation was found between opiate requirements in the PACU and pain at home 24 h after SPSG. Based on these results, it does not seem possible to predict intense pain at home from pain profile and morphine requirement during the immediate postoperative period. [ABSTRACT FROM AUTHOR]
