AI Article Synopsis

  • The study aimed to assess how intraoperative liposomal bupivacaine (LB) affects pain management after surgery in adolescent idiopathic scoliosis (AIS) patients, measuring factors like opioid use, mobility, and hospital stay length.
  • 119 AIS patients were divided into two groups: one receiving LB along with standard pain management and the other receiving only standard care, with results showing significantly lower opioid consumption and shorter hospital stays in the LB group.
  • Findings indicated that LB led to less opioid use, quicker recovery (discharge on average by postoperative day 2), and better post-surgery ambulation without notable differences in pain scores or nausea.

Article Abstract

Study Design: Retrospective controlled cohort.

Objective: To evaluate the effect of intraoperative liposomal bupivacaine (LB) infiltration on postsurgical pain management in adolescent idiopathic scoliosis (AIS) patients by analyzing postoperative opioid consumption, ambulation, and length of stay (LOS).

Summary Of Background Data: Optimal postoperative pain control for AIS patients undergoing posterior spinal fusion (PSF) is challenging. Multimodal pain management protocols provide adequate analgesia while decreasing opioid consumption. LB was recently approved for pediatric patients; however, use in AIS patients is understudied.

Methods: 119 consecutive patients with AIS who underwent PSF were included. Patients were divided into 2 groups: patients who received LB as erector spinae block in addition to the standard postoperative pain management protocol (Group A), and patients who received only the standard postoperative pain protocol (Group B). Oral morphine equivalents, intravenous opioid and valium consumption, pain scores (VAS), nausea/vomiting, ambulation distance and LOS were assessed.

Results: Group A experienced significantly lower total opioid consumption compared to Group B (44.5 mg vs. 70.2 mg). Morphine use was lower in Group A on postoperative day (POD) 0, and oxycodone use was lower in Group A on PODs 1 and 2. There was a higher proportion of patients who used only oral opioids in Group A (81% vs. 41%). Of patients requiring any intravenous opioids, 79% did not receive LB. A significantly higher proportion of LB patients were discharged on POD 2 (55% vs. 27%); therefore, LOS was shorter for Group A. Group A ambulated further postoperatively. There were no differences in pain scores, valium requirements or nausea/vomiting.

Conclusions: LB was associated with decreased total opioid use, shorter LOS, and improved ambulation in AIS patients undergoing PSF. Including LB in multimodal pain management protocols proved effective in reducing opioid use while increasing mobilization in the immediate postoperative period.

Level Of Evidence: 3.

Background: Delirium is a condition characterized by an acute and transient disturbance in attention, cognition, and consciousness. It is increasingly prevalent at the end of life in patients with cancer. While non-pharmacological nursing interventions are essential for delirium prevention, their effectiveness in terminally ill patients with cancer remains unclear.

Osteoarthritis of the wrist presents complex surgical challenges. A wide variety of surgical options are available when conservative management fails to provide adequate pain relief. Despite advancements in management, such as modifications of partial wrist arthrodesis techniques and increasing use of total wrist replacements, in most scenarios there is no single preferred option.

Necrotizing enterocolitis (NEC) is a relatively rare but very severe gastrointestinal disease primarily affecting very preterm infants. NEC is characterized by excessive inflammation and ischemia in the intestines, and is associated with prolonged, severe visceral pain. Despite its recognition as a highly painful disease, current pain management for NEC is often inadequate, and research on optimal analgesic therapy for these patients is lacking.

Background: The analgesic efficacy of esketamine combined with butorphanol in thoracoscopic surgery remains unclear.

Aim: This study explored the effects of perioperative esketamine combined with butorphanol versus butorphanol alone on acute and chronic postoperative pain in patients who underwent video-assisted lobectomy.

Method: A total of 181 patients were enrolled, with 90 in the esketamine-butorphanol group (Group BK) receiving intraoperative esketamine infusion and postoperative patient-controlled intravenous analgesia (PCIA) (esketamine 1.
