ABSTRACT
AIM: To explore the effects of an anterior quadratus lumborum block (QLB) on opioid consumption, pain, nausea, and vomiting (PONV) after ambulatory laparoscopic cholecystectomy. METHODS: This randomized controlled study recruited 70 patients scheduled for ambulatory laparoscopic cholecystectomy from January 2018 to March 2019. The participants were randomly allocated to one of the following groups: 1) anterior QLB (n=25) with preoperative ropivacaine 3.75 mg/mL, 20 mL bilaterally; 2) placebo QLB (n=22) with preoperative isotonic saline, 20 mL bilaterally; and 3) controls (n=23) given only standard intravenous and oral analgesia. The primary endpoint was opioid analgesic consumption. The secondary endpoints were pain (numeric rating scale 0-10) and PONV (scale 0-3, where 0=no PONV and 3=severe PONV). Assessments were made up to 48 hours postoperatively. RESULTS: The groups did not significantly differ in opioids consumption and reported pain at 1, 2, 24, and 48 hours postoperatively. PONV in the QLB group was lower than in the placebo and control groups. CONCLUSION: Preoperative anterior QLB for laparoscopic cholecystectomy did not affect postoperative opioid requirements and pain. However, anterior QLB may decrease PONV.

OBJECTIVE: The purpose of our study was to explore the local learning processes and to improve in situ team training in the primary care emergency teams with a focus on interaction. DESIGN, SETTING AND SUBJECTS: As participating observers, we investigated locally organised trainings of teams constituted ad hoc, involving nurses, paramedics and general practitioners, in rural Norway. Subsequently, we facilitated focus discussions with local participants. We investigated what kinds of issues the participants chose to elaborate in these learning situations, why they did so, and whether and how local conditions improved during the course of three and a half years. In addition, we applied learning theories to explore and challenge our own and the local participants' understanding of team training. RESULTS: In situ team training was experienced as challenging, engaging, and enabling. In the training sessions and later focus groups, the participants discussed a wide range of topics constitutive for learning in a sociocultural perspective, and topics constitutive for patient safety culture. The participants expanded the types of training sites, themes and the structures for participation, improved their understanding of communication and developed local procedures. The flexible structure of the model mirrors the complexity of medicine and provides space for the participants' own sense of responsibility. CONCLUSION: Challenging, monthly in situ team trainings organised by local health personnel facilitate many types of learning. The flexible training model provides space for the participants' own sense of responsibility and priorities. Outcomes involve social and structural improvements, including a sustainable culture of patient safety. KEY POINTS Challenging, monthly in situ team trainings, organised by local health personnel, facilitate many types of learning. The flexible structure of the training model mirrors the complexity of medicine and the realism of the simulation sessions. Providing room for the participants' own priorities and sense of responsibility allows for improvement on several levels. The participants demonstrated a consistent, long-term motivation to strengthen safety, both for their patients and for themselves.
