Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, that was first recognized in Wuhan, China, in December 2019. Currently, the World Health Organization (WHO) has defined the infection as a global pandemic and there is a health and social emergency for the management of this new infection. While most people with COVID-19 develop only mild or uncomplicated illness, approximately 14% develop severe disease that requires hospitalization and oxygen support, and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by the acute respiratory distress syndrome (ARDS), sepsis and septic shock, and multiorgan failure. This consensus document has been prepared on evidence-informed guidelines developed by a multidisciplinary panel of health care providers from four Spanish scientific societies (Spanish Society of Intensive Care Medicine [SEMICYUC], Spanish Society of Pulmonologists [SEPAR], Spanish Society of Emergency [SEMES], Spanish Society of Anesthesiology, Reanimation, and Pain [SEDAR]) with experience in the clinical management of patients with COVID-19 and other viral infections, including SARS, as well as sepsis and ARDS. The document provides clinical recommendations for the noninvasive respiratory support (noninvasive ventilation, high flow oxygen therapy with nasal cannula) in any patient with suspected or confirmed presentation of COVID-19 with acute respiratory failure. This consensus guidance should serve as a foundation for optimized supportive care to ensure the best possible chance for survival and to allow for reliable comparison of investigational therapeutic interventions as part of randomized controlled trials.

Pneumonia caused by coronavirus, which originated in Wuhan, China, in late 2019, has been spread around the world already becoming a pandemic. Unfortunately, there is not yet a specific vaccine or effective antiviral drug for treating COVID-19. Many of these patients deteriorate rapidly and require intubation and are mechanically ventilated, which is causing the collapse of the health system in many countries due to lack of ventilators and intensive care beds. In this document we review two simple adjuvant therapies to administer, without side effects, and low cost that could be useful for the treatment of acute severe coronavirus infection associated with acute respiratory syndrome (SARS-CoV-2). VitaminC, a potent antioxidant, has emerged as a relevant therapy due to its potential benefits when administered intravenous. The potential effect of vitaminC in reducing inflammation in the lungs could play a key role in lung injury caused by coronavirus infection. Another potential effective therapy is ozone: it has been extensively studied and used for many years and its effectiveness has been demonstrated so far in multiples studies. Nevertheless, our goal is not to make an exhaustive review of these therapies but spread the beneficial effects themselves. Obviously clinical trials are necessaries, but due to the potential benefit of these two therapies we highly recommended to add to the therapeutic arsenal.

To perform a meta-analysis on the use of combined epidural-intrathecal analgesia during labor, including intrathecal fentanyl and/or morphine compared to usual epidural techniques.

Intraoperative evaluation of analgesia remains today often based on heart rate and arterial pressure fluctuations. None of these parameters is specific. Incorrect handling during this process may increase surgical morbi-mortality of the patients and their acute postoperative pain. The aim of this study was to evaluate the impact of intraoperative analgesia controlled by pupillometry on postoperative analgesic consumption and the pain intensity in the first 12h in the hospital room, after major gynecological surgery.

There is an almost unanimous consensus on the management of the direct new oral anticoagulants, dabigatran, rivaroxaban, and apixaban in elective surgery. However, this general consensus does not exist in relation with the direct new oral anticoagulants use in emergency surgery, especially in the bleeding patient. For this reason, a literature review was performed using the MEDLINE-PubMed. An analysis was made of the journal articles, reviews, systematic reviews, and practices guidelines published between 2000 and 2014 using the terms “monitoring” and “reversal”. From this review, it was shown that the routine tests of blood coagulation, such as the prothrombin time and activated partial thromboplastin time, have a limited efficacy in the perioperative control of blood coagulation in these patients. There is currently no antidote to reverse the effects of these drugs, although the possibility of using concentrated prothrombin complex and recombinant activated factor vii has been suggested for the urgent reversal of the anticoagulant effect.

Tranexamic acid (TXA) is an antifibrinolytic drug used to reduce bleeding in mortality risk situations such as trauma, cardiovascular surgery, and orthopedic surgery. The objective is to evaluate the effectiveness and safety of TXA in reducing surgery bleeding in hip arthroplasty through a systematic review of literature.

The aim of the study was to assess the effectiveness of ultrasound-guided transversalis fascia plane block (TFP) compared to anterior transversus abdominis plane block (TAP-A) for post-operative analgesia in outpatient unilateral inguinal hernia repair.

A case is presented on a patient who underwent left single lung transplantation for emphysema type COPD. There was early graft dysfunction gradeiii during the immediate postoperative period, which required the implantation of an extracorporeal membrane oxygenator (ECMO). Respirator ventilatory parameters were adjusted to avoid lung distension, low tidal volume (Vc) (280ml), high respiratory rates (20rpm), and a positive pressure at end expiration (PEEP) level of 8cmH2O. On monitoring the pulmonary tidal volume distribution by bedside electrical impedance tomography (EIT), it was noted that most of the tidal volume was distributed in the native lung emphysema. An alveolar recruitment manoeuvre was performed, under control of the EIT, that enabled the current volume and distribution and the pressures required to ventilate the transplanted lung to be observed.
