There are no reports of human research on continuous epidural contrast injection, and there are no definite methods to investigate the spread of drugs injected continuously into the epidural space. We investigated the feasibility of continuous epidural contrast injection in patients undergoing computed tomography (CT)-guided therapy. In this study, a combination of a contrast agent mixed with 0.75% ropivacaine was used as the test drug. The main outcome evaluated was the feasibility of continuous epidural contrast imaging by CT scan following epidural injection of a contrast agent with 0.75% ropivacaine. We studied three patients who underwent CT-guided procedures and found that continuous epidural contrast injection was possible without any deleterious effects, such as an allergic reaction. The spread of the contrast agent was not consistent with the level of the clinical analgesic effect. Continuous epidural contrast injection is a feasible procedure. The results of our study might contribute to future research on continuous epidural contrast administration, as well as provide patients with superior analgesia.

Acute pain service was consulted for acute pain management in a 40-year-old male who had sustained multiple bilateral rib fractures following a fall injury. In addition to the rib fractures, the patient had also experienced injuries to his lungs and spinal column, both of which required surgeries. Considering the significant nature of pain due to his rib fractures, a multimodal pain management approach that included both pharmacological and non-pharmacological strategies was utilized.

Objective: To evaluate the feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for performing adnexectomy and high uterosacral ligament suspension (HUSLS) after vaginal hysterectomy (VH) under epidural anesthesia.
Method: This was a retrospective case series of 42 women who underwent VH for stage II or greater apical prolapse according to pelvic organ prolapse quantification (POP-Q); however, adnexectomy could not performed and replace the vNOTES technique. The procedure continued with vNOTES adnexectomy and bilateral HUSLS under epidural anesthesia.

Background And Objective: Pectus excavatum is a common congenital chest wall abnormality characterized by a concave appearance of the chest, and minimally invasive repair of pectus excavatum (MIRPE) is the surgical treatment of choice. A rapidly growing field of research is pain management in children undergoing MIRPE, with many shifts in practice occurring over the last decade. The primary objectives of this narrative review are to describe current methods of perioperative pain management and the development of enhanced recovery after surgery (ERAS) to improve the experience of patients undergoing MIRPE.
