4 kPa [7.7-12.6]), compared with non-survivors (Sao 88% [80-92%]; Pao /Fio ratio 8.5 kPa [7.1-11.5]). Patients requiring ECMO because of asthma were more likely to survive (95% survival rate (95% CI, 91-99%), compared with a survival of 71% (95% CI, 69-74%) in patients with respiratory failure attributable to other diagnoses. A national ECMO service can achieve good short-term outcomes for patients with undifferentiated respiratory failure refractory to conventional management. NCT03979222. NCT03979222. Data on UK obstetric anaesthetic practice between 2009 and 2014 were collected by the Obstetric Anaesthetists' Association's National Obstetric Anaesthetic Database. This database provides information on workload, variation in practice, and complication rates. During 2009-14, data were submitted by 190 UK hospitals. The number of hospitals that submitted data each year ranged between 114 and 145. During this 6 yr period, between 27 and 35 data items were requested, although not all hospitals submitted information on all data items. The dataset was assessed for quality and only those data items with acceptable quality were analysed. The dataset contains information on 3 030 493 deliveries, 770 545 Caesarean sections, 623 050 women with labour neuraxial analgesia, and 61 121 general anaesthetics for Caesarean section. https://www.selleckchem.com/products/erastin2.html There was increased use of patient-controlled regimens for labour neuraxial analgesia over the 6 yr period. The mean rate of general anaesthesia used for Caesarean section was 8.75% (95% confidence interval, 8.26-9.24%). The rate of failed intubation for general anaesthesia for Caesarean section was one in 379. Inadvertent dural puncture rates varied between hospitals with a mean of 1.2% (95% confidence interval, 1.02-1.37%). The rate of a high neuraxial block causing unconsciousness was one in 6667 for all blocks. This unique large dataset provides a valuable insight of obstetric anaesthetic activity in the UK. Although missing data may place limitations on interpretation, it provides comparative estimates for the rates of rare complications and highlights variations in practice in time and place.

Treatment of complex proximal humerus fractures (PHFs) in the elderly should provide early mobilization to maintain autonomy and self-care possibility, avoiding further surgery for complications. Nowadays, there is not a gold standard for treatment. Aim of our study was to review our experience with the use of Reverse Total Shoulder Arthroplasty (RTSA) for the treatment of these fractures in the elderly, evaluating complications and functional results. Ninety-one patients older than 65 were treated with RTSA at our Institute between June 2005 and December 2017 there were 14 males and 77 females, with a mean age of 76 years (range 65-87 years). There were 58 fractures (20 Neer 3, 38 Neer 4) and 33 fracture-dislocations (7 Neer 3, 26 Neer 4). Complications were recorded, and functional outcomes were evaluated using the DASH score and Constant score (CS). Twenty-three complications occurred 8 cases of scapular notching, 5 neurologic palsies, 4 dislocations, 3 intraoperative diaphyseal fractures, and subclaf autonomy in daily activities, RTSA effectively treats complex PHFs. The incidence of complications requiring revision surgery is low and functional results are satisfactory and predictable. In elderly with inadequate bone stock and needing early recovery of autonomy in daily activities, RTSA effectively treats complex PHFs. The incidence of complications requiring revision surgery is low and functional results are satisfactory and predictable.In isolated high energy pelvic ring injuries, early surgical and nonsurgical fixation belongs to the rescue tools required for rapid recovery. With the increasing use of pelvic binders on scene, these patients frequently arrive in a better condition at the level I trauma centre than without any measures of immobilisation. We describe our surgical tools to achieve rapid fixation within the first hours after arrival, taking into account if additional injuries or special stations are relevant. Application of supraacetabular Schanz screws is usually performed under image intensifier guidance. The aim of this study was to perform it without imaging, with the hypothesis that, respecting anatomical landmarks, pre- and intraoperative fluoroscopy can be avoided. Insertion of the supra-acetabular Schanz screws was performed by two trauma surgery residents in a study sample of 14 human adult cadavers which had been embalmed by use of Thiel`s method. With cadavers placed in supine position, the anterior superior iliac spine (ASIS) was palpated. Starting from this landmark, 2cm were measured in a distal and 2cm in the medial direction. At this point, a 2cm long oblique skin incision was performed. Through this approach, 150mm Schanz screws were drilled bilaterally into the supra-acetabular corridor with an angulation of 20° to distal as well as 20° to medial. Following screw application, combined obturator oblique-outlet views (COOO) were taken bilaterally in each specimen by use of an Arcadis© Orbic 3D imaging. According to the described anatomical data, we defined a 2-2-2-20-20 concept, starting with a 2 cm skin incision 2 cm distal and 2 cm medial to the ASIS with a drill angulation of 20° inferior and 20° lateral orientation. Using this technique, all Schanz screws could be sufficiently inserted without intraprocedural x-ray imaging. The SARS-CoV-2 pandemic conditions high mortality rates in hospitalized elderly. Currently, a few studies include octogenarian patients and none of them analyze the impact of functional status on this health outcome. Our objective is to describe the characteristics of patients older than 80 years hospitalized for coronavirus disease 2019 (COVID-19), to determine the mortality rate and to identify associated factors. Prospective observational study carried out on patients over 80 years admitted for COVID-19 in a Geriatrics Service. Sociodemographic, clinical, functional, mental, analytical, radiological, therapeutic and healthcare variables were collected. The factors associated with in-hospital lethality were analyzed by bivariate analysis. 58 cases with laboratory-confirmed COVID-19 were included, mean age 88.3±5.4 years, 69% women, 65.5% moderate-severe cognitive impairment and previous Barthel index 40.66±36. The main symptoms were fever (60,3%), dyspnea (53.4%) and deterioration of functional condition (50%).
