RESUMO
Since December 2019 a novel coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2) has rapidly spread around the world resulting in an acute respiratory illness pandemic. The immense challenges for clinicians and hospitals as well as the strain on many healthcare systems has been unprecedented.The majority of patients present with mild symptoms of coronavirus disease 2019 (COVID-19); however, 5-8% become critically ill and require intensive care treatment. Acute hypoxemic respiratory failure with severe dyspnea and an increased respiratory rate (>30/min) usually leads to intensive care unit (ICU) admission. At this point bilateral pulmonary infiltrates are typically seen. Patients often develop a severe acute respiratory distress syndrome (ARDS).So far, remdesivir and dexamethasone have shown clinical effectiveness in severe COVID-19 in hospitalized patients. The main goal of supportive treatment is to ascertain adequate oxygenation. Invasive mechanical ventilation and repeated prone positioning are key elements in treating severely hypoxemic COVID-19 patients.Strict adherence to basic infection control measures (including hand hygiene) and correct use of personal protection equipment (PPE) are essential in the care of patients. Procedures that lead to formation of aerosols should be carried out with utmost precaution and preparation.

Since December 2019, the novel coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome - Corona Virus-2) has been spreading rapidly in the sense of a global pandemic. This poses significant challenges for clinicians and hospitals and is placing unprecedented strain on the healthcare systems of many countries. The majority of patients with Coronavirus Disease 2019 (COVID-19) present with only mild symptoms such as cough and fever. However, about 6â% require hospitalization. Early clarification of whether inpatient and, if necessary, intensive care treatment is medically appropriate and desired by the patient is of particular importance in the pandemic. Acute hypoxemic respiratory insufficiency with dyspnea and high respiratory rate (>â30/min) usually leads to admission to the intensive care unit. Often, bilateral pulmonary infiltrates/consolidations or even pulmonary emboli are already found on imaging. As the disease progresses, some of these patients develop acute respiratory distress syndrome (ARDS). Mortality reduction of available drug therapy in severe COVID-19 disease has only been demonstrated for dexamethasone in randomized controlled trials. The main goal of supportive therapy is to ensure adequate oxygenation. In this regard, invasive ventilation and repeated prone positioning are important elements in the treatment of severely hypoxemic COVID-19 patients. Strict adherence to basic hygiene, including hand hygiene, and the correct wearing of adequate personal protective equipment are essential when handling patients. Medically necessary actions on patients that could result in aerosol formation should be performed with extreme care and preparation.

Delirium is the most common form of cerebral dysfunction in intensive care patients and is a medical emergency that must be avoided or promptly diagnosed and treated. According to current knowledge the development of delirium seems to be caused by an interplay between increased vulnerability (predisposition) and simultaneous exposure to delirogenic factors. Since delirium is often overlooked in the clinical routine, a continuous screening for delirium should be performed. Due to the close connection between delirium, agitation and pain, sedation and analgesia must be evaluated at least every 8â¯h analogous to delirium screening. According to current knowledge, a multifactorial and multiprofessional approach is favored in the prevention and treatment of delirium. Non-pharmaceutical interventions through early mobilization, reorientation, sleep improvement, adequate pain therapy and avoidance of polypharmacy are of great importance. Depending on the clinical picture, different substances are used in symptom-oriented drug treatment of delirium. In order to achieve these diagnostic and therapeutic goals, an interdisciplinary treatment team consisting of intensive care, intensive care physicians, ward pharmacists, physiotherapists, nutrition specialists and psychiatrists is necessary in order to meet the requirements of the patient and their relatives.

Surgically induced fire is a life-threatening hazard; this topic has received little attention, although only 3 factors, the so-called fire triad, are needed for surgical fires to occur: an oxidizer, fuel and an ignition source. This systematic review aims to determine the impact of each component and to delegate every staff member an area of responsibility, thus ensuring patient health through prevention or protection. The trial was registered in Prospero CRD42018082656. A database search of eligible, preferably evidence-based studies was conducted. The Robins-I tool for assessing the risk of bias revealed a moderate risk of bias. Due to insufficient data, the main findings of these studies could not be summarized through a quantitative synthesis; therefore, a qualitative synthesis is outlined. The results are summarized according to the roles of the fire triad and discussed. (1) Role of the oxidizer: oxygen is the key component of the triad. Safe oxygen delivery is important. An oxygen-enriched environment (ORE) is caused by draping and is preferably prevented by suctioning. Fuel characteristics are affected by varying oxygen concentrations. (2) Role of the ignition source: electrocauterization is the most common ignition source, followed by lasers. Less common ignition sources include fiberoptic cables and preparative solutions, petrol or acetone. (3) Role of the fuel: surgical drapes are one of the most common fuels for surgical fires followed by the patient's hair and skin. Skin preparation solutions are among the less common fuels. Many fire-resistant materials have been tested that do not remain fire resistant in ORE. It was concluded that the main problem is defining the real extent of this hazard. Exact numbers and exact condition protocols are needed; therefore, standardized registration of every fire and future studies with much evidence are needed. Immediate prevention consists of close attention to patient safety to prevent surgical fires from happening.

Due to the great advantages, it is not possible to imagine current practice in anesthesia without the adminstration of muscle relaxants. For a long time the administration of succinylcholine for rapid sequence induction (RSI) was considered to be the state of the art for patients at risk for aspiration. The favorable characteristics are, however, accompanied by many, sometimes severe side effects. Due to the development of non-depolarizing muscle relaxants, in particular rocuronium in combination with sugammadex, there is the possibility to achieve a profile of action similar to succinylcholine with low side effects. After the introduction of sugammadex onto the market, further substances were conceived, which enable a complete encapsulation of muscle relaxants. Calabadion is a very promising new substance for the antagonization of muscle relaxants, which can antagonize the action of steroid as well as benzylisoquinoline types. In the USA new muscle relaxants are currently being tested, which have a rapid onset and the effect can be reversed by Lcysteine. One of the most promising substances is gantacurium, which is currently being tested in the USA in phase III trials. It remains to be seen whether these muscle relaxants, which are not yet on the market and drugs for reversal of neuromuscular blockade have the potential to become a real alternative to the combination of rocuronium and sugammadex.

We report the rare case of an in situ fracture of a spinal needle within the setting of repeated caesarean delivery in a 28-year-old pregnant woman and discuss the responsible underlying factors. In particular, a wrong technique, limited experience, difficulties to identify the anatomical landmarks, as well as the use of spinal needles smaller than 25 G might promote such a complication. In order to ensure the stability of the spinal needle and to avoid an in situ fracture, the spinal needle should be never moved without the stylet. In case of repeated bone contact, a well-experienced anaesthetist should be consulted, the spinal needle should be replaced and the use of ultrasound is recommended. Next, the use of an atraumatic spinal needle greater than 27 G should be considered to facilitate intrathecal puncture and to avoid the in situ fracture of a spinal needle. Within this context, the risk of post-spinal puncture headache should be balanced. If an in situ fracture of a spinal needle happens, its subsequent removal should be planned without delay by an interdisciplinary team and the anaesthetic method should be chosen with consideration of patient-specific risk factors.

BACKGROUND: Inguinal hernia repair is the most frequently performed surgical procedure in infants and children. Especially in premature infants, prevalence reaches up to 30% in coincidence with high rates of incarceration during the first year of life. These infants carry an increased risk of complications due to general anesthesia. Thus, spinal anesthesia is a topic of growing interest for this group of patients. We hypothesized that spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants even at high risk and cases of incarceration. METHODS: Between 2003 and 2013, we operated 100 infants younger than 6 months with inguinal hernia. Clinical data were collected prospectively and retrospectively analyzed. Patients were divided into two groups depending on anesthesia procedure (spinal anesthesia, Group 1 vs. general anesthesia, Group 2). RESULTS: Spinal anesthesia was performed in 69 infants, and 31 infants were operated in general anesthesia, respectively. In 7 of these 31 infants, general anesthesia was chosen because of lumbar puncture failure. Infants operated in spinal anesthesia were significantly smaller (54 ± 4 vs. 57 ± 4 cm; p = 0.001), had a lower body weight (4,047 ± 1,002 vs. 5,327 ± 1,376 g; p < 0.001) and higher rate of prematurity (26 vs. 4%; p = 0.017) compared to those operated in general anesthesia. No complications related to surgery or to anesthesia were found in both groups. The number of relevant preexisting diseases was higher in Group 1 (11 vs. 3%; p = 0.54). Seven of eight emergent incarcerated hernia repairs were performed in spinal anesthesia (p = 0.429). CONCLUSIONS: Spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants, especially in high-risk premature infants and in cases of hernia incarceration.

BACKGROUND: To date, only limited data exist about the use of xenon as an anaesthetic agent in patients undergoing cardiac surgery. The favourable cardio- and neuroprotective properties of xenon might attenuate postoperative complications, improve outcome, and reduce the incidence of delirium. Thus, the aims of this study were to investigate the feasibility and safety of balanced xenon anaesthesia in patients undergoing cardiac surgery and to gather pilot data for a future randomized multicentre study. METHODS: Thirty patients undergoing elective coronary artery bypass grafting were enrolled in this randomized, single-blind controlled trial. They were randomized to receive balanced general anaesthesia with either xenon (45-50 vol%) or sevoflurane (1-1.4 vol%). The primary outcome was the occurrence of adverse events (AEs). Secondary outcome parameters were feasibility criteria (bispectral index, perioperative haemodynamic, and respiratory profile) and safety parameters (dosage of study treatments, renal function, intraoperative blood loss, need for inotropic support, regional cerebral tissue oxygenation). Furthermore, at predefined time points, systemic and pulmonary haemodynamics were assessed by the use of a pulmonary artery catheter. RESULTS: There were no patient characteristic differences between the groups. Patients undergoing xenon anaesthesia did not differ with respect to the incidence of AE (6 vs 8, P=0.464) compared with the sevoflurane group. No differences were detected regarding secondary feasibility and safety criteria. The haemodynamic and respiratory profile was comparable between the treatment groups. CONCLUSIONS: Balanced xenon anaesthesia is feasible and safe compared with sevoflurane anaesthesia in patients undergoing coronary artery bypass surgery. Acronym CARDIAX: A pre- and post-coronary artery bypass graft implantation disposed application of xenon. Clinical trial registration ClinicalTrials.gov: NCT01285271; EudraCT-number: 2010-023942-63.

BACKGROUND: Previously, we showed a significant difference in the measurements of hypnotic depth by the bispectral index (BIS) and auditory-evoked potentials (AEPs) using the A-line autoregressive index during xenon anaesthesia. In the present study, we evaluate the alternative AEP-based auditory-evoked potential index (aepEX) for the measurement of hypnotic depth in patients undergoing general anaesthesia with xenon. METHODS: Forty-two patients undergoing elective abdominal surgery were enrolled in this controlled, double-blinded, randomized, clinical study. Patients were randomized to receive either xenon (n=21) or sevoflurane anaesthesia (n=21). During anaesthesia, BIS values were recorded simultaneously with the aepEX monitoring. The anaesthetist performing the anaesthesia was blinded to the hypnotic depth monitors. After surgery, the incidence of recalls and awareness was evaluated. RESULTS: Patients' characteristics such as gender, age, and weight did not differ between the groups. The aepEX and BIS values behaved similarly during anaesthesia. The comparison of aepEX values during xenon and sevoflurane anaesthesia revealed significantly lower aepEX values in the xenon group after 25 min [xenon: 32.9 (4.8) vs sevoflurane: 39.3 (9.0); P=0.008] and after 35 min [xenon: 31.4 (6.6) vs sevoflurane: 37.0 (6.8); P=0.012]. During anaesthesia, aepEX values correlated with the clinical evaluation of depth of anaesthesia (e.g. >20% changes of the baseline arterial pressure or heart rate, spontaneous breathing and/or intolerance of mechanical ventilation, coughing, abdominal pressing, sweating, eye tearing). CONCLUSIONS: We found the aepEX monitor to provide index in the range of adequate depth of xenon anaesthesia, when combined with remifentanil infusion in intubated patients undergoing elective abdominal surgery.

BACKGROUND: Postoperative hypoxemia is a common complication in the anesthesia recovery room (ARR), which is predominantly based on the development of atelectasis, excessive intraoperative fluid shift and insufficient ventilation. The goal of this prospective observational study was to compare the effect of standard oxygen administration via a face mask with oxygen administration using the EzPAP® system, a device which additionally provides a positive end-expiratory pressure (PEEP). METHODS: This study included 210 patients with postoperative hypoxemia (S(p)O(2) < 93%) subdivided into the control group (105 patients) and the EzPAP group (105 patients). Postoperative residual paralysis was excluded using relaxometry and a train of four (TOF) ratio of 0.9 was assumed to ensure sufficient recovery of respiratory function from neuromuscular blockade. Patients who received a reversal of neuromuscular blockade were excluded. In cases of hypoxemia (S(p)O(2) < 93%) control patients were treated with oxygen (6 l/min) using a face mask, whereas the EzPAP group received oxygen using the EzPAP® system. In order to adjust the PEEP in the EzPAP group, the O(2) flow was verified and measured by a manometer. After 1 h of oxygen therapy, the oxygen supply was stopped. In cases of reoccurring hypoxemia (S(p)O(2) < 93%, persistence > 5 min), the oxygen therapy was restarted in both groups via a facemask. Both groups were compared using repeat measurement analysis of variance (ANOVA), the unpaired t-test, the Mann-Whitney U-test, Fisher's exact test and the χ(2)-test. The correlation of O(2) flow and PEEP was evaluated by regression analysis and p < 0.05 was considered to be statistically significant. Apart from this a subgroup analysis was performed depending on body-mass index (BMI), American Society of Anesthesiologists (ASA) classification, intraoperative airway management, the use of neuromuscular blocking agents and co-existing disorders, e.g. chronic obstructive lung disease (COLD), obesity and chronic heart failure. RESULTS: All patients were equally distributed between both groups with respect to demographic data, ASA classification, BMI, co-existing disorders and surgical procedures. The S(p)O(2) values did not differ between the EzPAP patients and the control group, except for 0.5 min after initiation of oxygen therapy: EzPAP group 96 ± 3.7% (mean ± standard deviation) versus the control group 93.8 ± 4.4% (p < 0.001). However, restarting oxygen therapy was less common in the EzPAP group (EzPAP group 25 versus control group 41, p = 0.03), as well as the occurrence of postoperative complications (EzPAP group 13 versus control group 25, p = 0.02), e.g. nosocomial pneumonia (0 versus 4) and wound infections (2 versus 3). Furthermore, patients with obesity and pulmonary disorders, such as COLD had a benefit from oxygen administration using the EzPAP device and showed higher postoperative than preoperative S(p)O(2) values. In contrast, the subgroup analysis of patients with heart failure did not reveal any differences between both groups and both groups did not differ in terms of time spent in the recovery room (EzPAP group 113 min versus control group 174.8 min, p = 0.2). CONCLUSIONS: In this observational study oxygen supply using the EzPAP® system appeared to be at least equally as effective in the therapy of postoperative hypoxemia compared to standard oxygen supply using a face mask. In patients with a high risk of postoperative hypoxemia, such as patients with obesity and/or pulmonary disorders, oxygen administration using the EzPAP® system possibly improves pulmonary oxygenation more effectively and is longer lasting compared to standard oxygen supply via a face mask. Hence, the EzPAP® system represents a well-tolerated, effective, cost-effective and easily operated tool to improve postoperative oxygenation. In order to investigate the possibilities of this promising tool more intensively, randomized clinical trials are warranted.

Urine neutrophil gelatinase-associated lipocalin (uNGAL) has been evaluated as a biomarker for AKI detection and adverse outcome in open and endovascular thoracoabdominal aortic aneurysm surgery. This observational, retrospective study included 52 patients. UNGAL was measured peri-operatively (48 h) and correlated with AKI requiring dialysis, tracheotomy and adverse outcome. Mean patients' age was 64.5 years. A total of 26.9% (n = 14) developed AKI, and 21.1% (n = 11) required dialysis, tracheotomy rate was 19.2% (n = 10) and in-hospital mortality rate was 7.6% (n = 4). uNGAL levels were related to AKI requiring dialysis at ICU (p = 0.0002), need for tracheotomy at baseline and admission on ICU (p = 0.0222, p = 0.0028, respectively), as well as adverse discharge modality (p = 0.0051, p = 0.0048, respectively). Diagnostic quality was good for uNGAL levels at admission to ICU regarding AKI requiring dialysis (sensitivity: 81.8% [48.2-97.7]; specificity: 87.8% [73.8-95.9]; area under the curve (AUC): 0.874 [0.752-0.949]). The diagnostic quality of uNGAL was favorable for the prediction of tracheotomy (sensitivity: 70.0% [34.8-93.3]; specificity: 83.3% [68.6-93.0]; AUC: 0.807 [0.674-0.903]) and adverse discharge (sensitivity: 77.8% [40.0-97.2]; specificity: 83.7% [69.3-93.2]; AUC: 0.817 [0.685-0.910]). uNGAL may be valuable as an post-operative predictor of AKI and adverse outcome after open and endovascular TAAA repair.

OBJECTIVES: This study aimed to compare visualisation of the vocal cords and performance of intubation by anaesthetists using four different laryngoscopes while wearing full chemical protective equipment. SETTING: Medical simulation center of a university hospital, department of anaesthesiology. PARTICIPANTS: 42 anaesthetists (15 females and 27 males) completed the trial. The participants were grouped according to their professional education as anaesthesiology residents with experience of <2 years or <5 years, or as anaesthesiology specialists with experience of >5 years. INTERVENTIONS: In a manikin scenario, participants performed endotracheal intubations with four different direct and indirect laryngoscopes (Macintosh (MAC), Airtraq (ATQ), Glidescope (GLS) and AP Advance (APA)), while wearing chemical protective gear, including a body suit, rubber gloves, a fire helmet and breathing apparatus. PRIMARY AND SECONDARY OUTCOME MEASURES: With respect to the manikin, setting time to complete 'endotracheal intubation' was defined as primary end point. Glottis visualisation (according to the Cormack-Lehane score (CLS) and impairments caused by the protective equipment, were defined as secondary outcome measures. RESULTS: The times to tracheal intubation were calculated using the MAC (31.4 s; 95% CI 26.6 to 36.8), ATQ (37.1 s; 95% CI 28.3 to 45.9), GLS (35.4 s; 95% CI 28.7 to 42.1) and APA (23.6 s; 95% CI 19.1 to 28.1), respectively. Intubation with the APA was significantly faster than with all the other devices examined among the total study population (p<0.05). A significant improvement in visualisation of the vocal cords was reported for the APA compared with the GLS. CONCLUSIONS: Despite the restrictions caused by the equipment, the anaesthetists intubated the manikin successfully within adequate time. The APA outperformed the other devices in the time to intubation, and it has been evaluated as an easily manageable device for anaesthetists with varying degrees of experience (low to high), providing good visualisation in scenarios that require the use of chemical protective equipment.

INTRODUCTION: Renal artery aneurysms represent a rare entity with an incidence of 0.3 - 1.3% in angiographies. Rupture of such aneurysms are rare. During pregnancy there is an increased risk of rupture with a high mortality for mother and child. We report the first case of rupture of a left renal artery aneurysm during delivery with survival of mother and child. CASE REPORT: Due to arrest of labor during a home birth, the patient was admitted to the hospital, where an immediate forceps extraction on account of fetal asphyxia was performed. Immediately after delivery a hypovolemic shock developed. Ultrasound examination showed a huge subsplenic hematoma. Emergency laparotomy revealed a ruptured renal artery aneurysm. The renal artery was ligated on the assumption of a lower pole vessel. Despite hemodynamic stability a drop in hemoglobin occurred the following day. Angiography showed no perfusion of the left kidney. A left nephrectomy was performed without complications. The further course was uneventful. Mother and child survived. CONCLUSIONS: Rupture of aneurysms of the splenic and renal artery during later stages of pregnancy, during delivery or after childbirth are possible etiologies in cases of unexplained shock and abdominal pain. An emergency angiography in such cases helps to reveal the underlying cause and renders possible a targeted operative approach.
