[Postoperative nausea and vomiting and opioid-induced nausea and vomiting: guidelines for prevention and treatment].
ABSTRACT Postoperative nausea and vomiting (PONV) causes patient discomfort, lowers patient satisfaction, and increases care requirements. Opioid-induced nausea and vomiting (OINV) may also occur if opioids are used to treat postoperative pain. These guidelines aim to provide recommendations for the prevention and treatment of both problems. A working group was established in accordance with the charter of the Sociedad Española de Anestesiología y Reanimación. The group undertook the critical appraisal of articles relevant to the management of PONV and OINV in adults and children early and late in the perioperative period. Discussions led to recommendations, summarized as follows: 1) Risk for PONV should be assessed in all patients undergoing surgery; 2 easy-to-use scales are useful for risk assessment: the Apfel scale for adults and the Eberhart scale for children. 2) Measures to reduce baseline risk should be used for adults at moderate or high risk and all children. 3) Pharmacologic prophylaxis with 1 drug is useful for patients at low risk (Apfel or Eberhart 1) who are to receive general anesthesia; patients with higher levels of risk should receive prophylaxis with 2 or more drugs and baseline risk should be reduced (multimodal approach). 4) Dexamethasone, droperidol, and ondansetron (or other setrons) have similar levels of efficacy; drug choice should be made based on individual patient factors. 5) The drug prescribed for treating PONV should preferably be different from the one used for prophylaxis; ondansetron is the most effective drug for treating PONV. 6) Risk for PONV should be assessed before discharge after outpatient surgery or on the ward for hospitalized patients; there is no evidence that late preventive strategies are effective. 7) The drug of choice for preventing OINV is droperidol.

ABSTRACT: Acute gastrointestinal (GI) dysfunction and failure have been increasingly recognized in critically ill patients. The variety of definitions proposed in the past has led to confusion and difficulty in comparing one study to another. An international working group convened to standardize the definitions for acute GI failure and GI symptoms and to review the therapeutic options. The Working Group on Abdominal Problems (WGAP) of the European Society of Intensive Care Medicine (ESICM) developed the definitions for GI dysfunction in intensive care patients on the basis of the available evidence and current understanding of the pathophysiology. Definitions for acute gastrointestinal injury (AGI) with its four grades of severity, as well as for feeding intolerance syndrome and GI symptoms (e.g. vomiting, diarrhoea, paralysis, high gastric residual volumes) are proposed. AGI is a malfunctioning of the GI tract in intensive care patients due to their acute illness. AGI grade I = increased risk of developing GI dysfunction or failure (a self-limiting condition); AGI grade II = GI dysfunction (a condition that requires interventions); AGI grade III = GI failure (GI function cannot be restored with interventions); AGI grade IV = dramatically manifesting GI failure (a condition that is immediately life-threatening). Current evidence and expert opinions regarding treatment of acute GI dysfunction are provided. State-of-the-art definitions for GI dysfunction with gradation as well as management recommendations are proposed on the basis of current medical evidence and expert opinion. The WGAP recommends using these definitions for clinical and research purposes.Intensive Care Medicine 03/2012; 38(3):384-94. DOI:10.1007/s00134-011-2459-y · 7.21 Impact Factor

ABSTRACT: Surgery of the posterior fossa and/or craniospinal region has a high rate of postoperative morbidity and mortality, which has rarely been described in the scientific literature. This review aims to describe the available evidence in the literature on the complications associated with this type of surgery and its neuroanesthesiological and/ or neurocritical management, as well as to highlight the predisposing factors that can increase the complications rate. Knowledge of the complications related to neurosurgical disorders of the posterior fossa could aid in their prevention or help in the selection of appropriate treatment that would minimize their consequences. A systematic literature search was made in Spanish and English for articles published between 1966 and 2012 in various databases. Articles considered important in the identified literature were reviewed. The most frequently described postoperative complications were vomiting and postoperative pain, followed by edema of the tongue and/or airway, involvement of the cranial nerves, and the development of cerebrospinal fluid fistulas. The remaining complications were reported as being uncommon. Posterior fossa and posterior cervical surgery produces higher morbidity and mortality than surgery of the supratentorial space. In addition to the complications involved in all craniotomies, infratentorial surgery has specific complications. Team work among all the specialties and staff involved in the care of these patients is essential to reduce the morbidity and mortality associated with these procedures.Revista espanola de anestesiologia y reanimacion 11/2012; 59S1:25-37.
