Rationale and study design for an Individualized PeriopeRative Open lung VEntilatory approach in Emergency Abdominal Laparotomy/scopy: study protocol for a prospective international randomized controlled trial.

BACKGROUND: Postoperative pulmonary complications (PPC) are the most frequent postoperative complications, with an estimated prevalence in elective surgery ranging from 20% in observational cohort studies to 40% in randomized clinical trials. However, the prevalence of PPCs in patients undergoing emergency abdominal surgery is not well defined. Lung-protective ventilation aims to minimize ventilator-induced lung injury and reduce PPCs. The open lung approach (OLA), which combines recruitment manoeuvres (RM) and positive end-expiratory pressure (PEEP) titration, aims to minimize areas of atelectasis and the development of PPCs; however, there is no conclusive evidence in the literature that OLA can prevent PPCs. The purpose of this study is to compare an individualized perioperative OLA with conventional standardized lung-protective ventilation in patients undergoing emergency abdominal surgery with clinical signs of intraoperative lung collapse. METHODS: Randomized international clinical trial to compare an individualized perioperative OLA (RM plus individualized PEEP and individualized postoperative respiratory support) with conventional lung-protective ventilation (standard PEEP of 5 cmH2O and conventional postoperative oxygen therapy) in patients undergoing emergency abdominal surgery with clinical signs of lung collapse. Patients will be randomised to open-label parallel groups. The primary outcome is any severe PPC during the first 7 postoperative days, including: acute respiratory failure, pneumothorax, weaning failure, acute respiratory distress syndrome, and pulmonary infection. The estimated sample size is 732 patients (366 per group). The final sample size will be readjusted during the interim analysis. DISCUSSION: The Individualized Perioperative Open-lung Ventilatory Strategy in emergency abdominal laparotomy (iPROVE-EAL) is the first multicentre, randomized, controlled trial to investigate whether an individualized perioperative approach prevents PPCs in patients undergoing emergency surgery.

Neuroleptic malignant syndrome in a postoperative patient: A case report.

Neuroleptic malignant syndrome is a rare medical emergency associated with the use of antipsychotics and other antidopaminergic drugs. There is no specific test, and diagnosis is based on high clinical suspicion and good differential diagnosis. A clinical picture consistent with hyperthermia, muscle rigidity, altered level of consciousness, together with signs of rhabdomyolysis in analytical studies and a history of taking neuroleptic drugs are the key elements in the detection of this entity. Due to its low incidence and potential mortality, it is essential to publish case reports of neuroleptic malignant syndrome in order to raise awareness of this entity and facilitate diagnostic suspicion when encountering a patient with compatible symptoms. The following is the case of a 79 year old patient with chronic alcohol consumption as the only history of interest, who was given a single dose of haloperidol after an episode of delirium in the postoperative period of conventional trauma surgery. She subsequently developed a picture of progressive deterioration of the level of consciousness, diaphoresis, generalized muscle rigidity, hyperthermia, together with severe metabolic acidosis, hyperlacticaemia, rhabdomyolysis, hypertransaminasemia and hypocalcemia. After ruling out other entities compatible with the clinical picture, neuroleptic malignant syndrome was given as the main diagnostic hypothesis. Diagnosis was confirmed after clinical and analytical improvement following treatment with dantrolene. The patient was discharged from hospital with no sequelae a few days after onset of the condition.

Síndrome neuroléptico maligno en paciente postoperada: a propósito de un caso / Neuroleptic malignant syndrome in a postoperative patient: a case report

El síndrome neuroléptico maligno es una emergencia médica poco frecuente asociada al uso de antipsicóticos y otros fármacos antidopaminérgicos. No se dispone de una prueba específica para su diagnóstico, basándose este en una alta sospecha clínica y la realización de un buen diagnóstico diferencial. Un cuadro clínico compatible, destacando la hipertermia, rigidez muscular, alteración del nivel de conciencia y signos de rabdomiolisis en los estudios analíticos, junto con el antecedente de la toma de fármacos neurolépticos, constituyen los elementos clave para la detección de esta entidad. Debido a su escasa incidencia y su potencial mortalidad, es primordial su conocimiento a través de series de casos descritos en la literatura para facilitar su sospecha diagnóstica ante un caso clínico compatible. A continuación, exponemos un caso de una paciente de 79 años con consumo crónico de alcohol como único antecedente de interés, que recibió una dosis única de haloperidol tras un cuadro de delirio en el contexto de un postoperatorio convencional de traumatología. Posteriormente, desarrolló un cuadro de deterioro progresivo del nivel de conciencia, diaforesis, rigidez muscular generalizada, hipertermia, junto a acidosis metabólica severa, hiperlactacidemia, rabdomiolisis, hipertransaminasemia e hipocalcemia. Tras excluir otras entidades compatibles con la clínica, el síndrome neuroléptico maligno se postuló como la principal hipótesis diagnóstica, reforzándose el diagnóstico tras la mejoría clínica y analítica evidente posterior al inicio del tratamiento con dantrolene. La paciente pudo, finalmente, ser dada de alta escasos días después del inicio del cuadro sin presentar secuelas.(AU)

Brain abscess due to Listeria monocytogenes after HELLP syndrome in a patient with antiphospholipid syndrome.

Objective To illustrate an unusual case of Listeria cerebral abscess. Material and methods A 32-year-old pregnant woman with thrombotic antiphospholipid syndrome (APS) received corticotherapy for two weeks due to hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome. After delivery she presented with neurological symptoms and fever. Results The MRI scan confirmed the presence of a brain abscess, and Listeria monocytogenes was isolated in blood cultures. After eight weeks of antibiotic treatment, the patient presented no sequelae. Conclusion L. monocytogenes should be included in the differential diagnosis of patients with fever and neurological dysfunction, especially in those with a recent history of corticotherapy.
