Review
Evidence-based management of pain after laparoscopic cholecystectomy: a PROSPECT review update.
Significant pain can be experienced after laparoscopic cholecystectomy. This systematic review aims to formulate PROSPECT (PROcedure SPECific Postoperative Pain ManagemenT) recommendations to reduce postoperative pain after laparoscopic cholecystectomy. ⋯ We recommend basic analgesic techniques: paracetamol + NSAID or cyclooxygenase-2 specific inhibitor + surgical site local anaesthetic infiltration. Paracetamol and NSAID should be started before or during operation with dexamethasone (GRADE A). Opioid should be reserved for rescue analgesia only (GRADE B). Gabapentanoids, intraperitoneal local anaesthetic, and transversus abdominis plane blocks are not recommended (GRADE D) unless basic analgesia is not possible. Surgically, we recommend low-pressure pneumoperitoneum, postprocedure saline lavage, and aspiration of pneumoperitoneum (GRADE A). Single-port incision techniques are not recommended to reduce pain (GRADE A).

Among patients undergoing emergency laparotomy, 30-day postoperative mortality is around 10-15%. The risk of death among these patients, however, varies greatly because of their clinical characteristics. We developed a risk prediction model for 30-day postoperative mortality to enable better comparison of outcomes between hospitals. ⋯ The NELA risk prediction model for emergency laparotomies discriminates well between low- and high-risk patients and is suitable for producing risk-adjusted provider mortality statistics.

There is a need for high quality research to improve perioperative patient care in Africa. The aim of this study was to understand the particular barriers to clinical research in this environment. ⋯ Barriers to successful participation in ASOS related to resource limitations and not motivation of the clinician investigators. Practical solutions to individual barriers may increase the success of multi-centre perioperative research in Africa.

Placement of local anaesthetic within the adductor canal using ultrasonography is an alternative to femoral nerve blocks for postoperative pain relief after knee joint replacement surgery. However, the effect of an inflated thigh tourniquet on the distribution of local anaesthetic within the adductor canal is unknown. The aim of this cadaveric study was to compare the distribution of radio-opaque dye within the adductor canal in the presence or absence of an inflated thigh tourniquet. ⋯ Application and inflation of thigh tourniquets significantly increased the combined superior-inferior dye distribution within the adductor canal of cadaveric limbs. There was insufficient evidence to suggest significant proximal spread of 25 ml of local anaesthetic to involve the motor branches of the femoral nerve. In some patients, the local anaesthetic may reach the popliteal fossa in close approximation to the sciatic nerve.

Multicenter Study Observational Study
Adoption of Lung Protective ventilation IN patients undergoing Emergency laparotomy: the ALPINE study. A prospective multicentre observational study.
Emergency abdominal surgery is associated with a high risk of postoperative pulmonary complications (PPCs). The primary aim of this study was to determine whether patients undergoing emergency laparotomy are ventilated using a lung-protective ventilation strategy employing tidal volume ≤8 ml kg-1 ideal body weight-1, PEEP >5 cm H2O, and recruitment manoeuvres. The secondary aim was to investigate the association between ventilation factors (lung-protective ventilation strategy, intraoperative FiO2, and peak inspiratory pressure) and the occurrence of PPCs. ⋯ Both intraoperative peak inspiratory pressure and FiO2 are independent factors significantly associated with development of a postoperative pulmonary complication in emergency laparotomy patients. Further studies are required to identify causality and to demonstrate if their manipulation could lead to better clinical outcomes.
