Perioperative acute kidney injury - cloaked and hidden - know your enemy.

Surgery and anaesthesia come with adverse effects. As obvious as it is, not all of them are considered frequently enough. It may seem reasonable because some of them kill instantly.

The effect of pre-emptive oral pregabalin on opioid consumption in patients undergoing laparoscopic sleeve gastrectomy with an analysis of intraoperative hemodynamic stability and quality of recovery: study protocol for a randomized, prospective, double-blind study.

Background: Obese patients undergoing laparoscopic sleeve gastrectomy (LSG) are particularly at risk of opioid-related side effects. To reduce patient exposure to opioids, multimodal analgesia, which involves the use of drugs of different classes, may be utilized. One of the drugs under consideration is pregabalin.

Successful Anesthetic Management for Obese Patients with Interstitial Lung Disease Undergoing Laparoscopic Sleeve Gastrectomy: A Bridge to Improved Lung Transplant Eligibility.

BACKGROUND Patients with obesity with interstitial lung diseases (ILD) are encouraged to lose weight, as it improves lung function and lung transplant eligibility. As exercise tolerance in these patients is low and weight gain is a common adverse effect of corticosteroids, bariatric surgery can be an effective method for the management of obesity in this patient group. However, perioperative complications in such high-risk patients remain a concern.

Improved oxygenation in prone positioning of mechanically ventilated patients with COVID-19 acute respiratory distress syndrome is associated with decreased pulmonary shunt fraction: a prospective multicenter study.

Background: Prone position is used in acute respiratory distress syndrome and in coronavirus disease 2019 (Covid-19) acute respiratory distress syndrome (ARDS). However, physiological mechanisms remain unclear. The aim of this study was to determine whether improved oxygenation was related to pulmonary shunt fraction (Q's/Q't), alveolar dead space (Vd/Vtalv) and ventilation/perfusion mismatch (V'/Q').

Comparison between multimodal and intraoperative opioid free anesthesia for laparoscopic sleeve gastrectomy: a prospective, randomized study.

Anesthesia for laparoscopic sleeve gastrectomy and perioperative management remains a challenge. Several clinical studies indicate that opioid-free anesthesia (OFA) may be beneficial, but there is no consensus on the most optimal anesthesia technique in clinical practice. The aim of our study was to assess the potential benefits and risks of intraoperative OFA compared to multimodal analgesia (MMA) with remifentanil infusion.

Malignant hyperthermia in Poland: A survey study.

Malignant hyperthermia (MH) is a life-threatening syndrome caused by sudden, uncontrolled skeletal muscle hypermetabolism in response to inhalation anesthetics and depolarizing relaxants. The estimated incidence of MH is between 1:10,000 and 1:250,000 anesthetic procedures. In Poland, due to lack of reporting, the incidence of MH is unknown.

Effect of Intramuscular Tramadol on the Duration of Clinically Relevant Sciatic Nerve Blockade in Patients Undergoing Calcaneal Fracture Fixation: A Randomized Controlled Trial.

Background: Calcaneal fracture fixation can generate severe postoperative pain and analgesia can be supported by a sciatic nerve block. However, following resolution of the sensory blockade, rebound pain may ensue. The aim of this study was to assess whether an incidental finding of two patients with an extension of the sciatic nerve block beyond 24 h following 100 mg of intramuscular tramadol administration could be confirmed.

Efficacy and Side Effect Profile of Intrathecal Morphine versus Distal Femoral Triangle Nerve Block for Analgesia following Total Knee Arthroplasty: A Randomized Trial.

(1) Background: The management of postoperative pain after knee replacement is an important clinical problem. The best results in the treatment of postoperative pain are obtained using multimodal therapy principles. Intrathecal morphine (ITM) and single-shot femoral nerve block (SSFNB) are practiced in the treatment of postoperative pain after knee replacement, with the most optimal methods still under debate.

Malignant hyperthermia in Mazovia Province - are we adequately prepared?

Introduction: Malignant hyperthermia (MH) is a life-threatening syndrome caused by sudden skeletal muscle hypermetabolism in response to inhalation anaesthetics and depolarising relaxants. The estimated incidence of MH is between 1 : 10,000 and 1 : 250,000 anaesthetic procedures. In Poland the incidence of MH is unknown.

DIC, SIC or CAC - the haemostatic profile in COVID-19 patients hospitalised in the intensive care unit: a single-centre retrospective analysis.

Introduction: Infection with SARS-CoV-2 in its most severe form leads to acute respiratory distress syndrome requiring mechanical ventilation under the conditions of the Intensive Care Unit (ICU). The state of hypercoagulation described in COVID-19 may deepen respiratory failure, leading to increased mortality. The aim of the presented study is to characterise the haemostatic profile based on the results of clotting system parameters and risk assessment of thromboembolic complications of patients hospitalised in the ICU.

Copeptin (CTproAVP) - A Biomarker of a Circulatory Impairment in Liver Transplant Recipients? A Prospective, Observational Study.

Background: Copeptin, an easily measured and stable surrogate marker of arginine vasopressin, is a biomarker of a homeostasis disorder and a circulatory impairment in a wide spectrum of morbidities. The aim of this study was to evaluate the potential of copeptin as a biomarker of a circulatory impairment in patients undergoing liver transplantation (LT).

Methods: This was a prospective, observational study.

COVID-19: coagulation disorders and anticoagulant treatment in patients hospitalised in ICU.

Patients hospitalized in the intensive care unit (ICU) due to the COVID-19 experience a high incidence (up to 43%) of venous thromboembolic events. While laboratory findings in COVID-19-associated coagulopathy (CAC) show increased D-dimer and fibrinogen levels, the abnormalities in standard coagulation tests and platelet count are minimal. Recent studies suggest contribution of fibrinolysis shutdown to this phenomenon.

Open kidney cancer surgery and perioperative cardiac arrhythmias.

Introduction: Although cardiac arrhythmias during anesthesia are often observed, the literature focuses mainly on cardio-thoracic surgery. We aimed to evaluate the incidence of arrhythmias appearing in the perioperative period in patients undergoing urological surgery and furthermore to define whether combining general with epidural anesthesia prevents them.

Material And Methods: The study included 50 adults, without a prior cardiac or arrhythmia history, undergoing an open kidney cancer surgery, who were randomly allocated to receive either general or combined epidural/general anesthesia.

What Do We Know about Early Management of Sepsis and Septic Shock in Polish Hospitals? A Questionnaire Study.

Background: Sepsis and septic shock are medical emergencies with a high risk of poor prognosis. We investigate the correspondence between Surviving Sepsis Campaign (SSC) guidelines and clinical practice in Poland, with special attention given to differences between ICU and non-ICU environments as well as regional variations within the country.

Methods: A web-based questionnaire study was performed on a random sample of 60 hospitals from the three most populated regions in Poland-Masovia, Silesia, and Greater Poland.

Assessment of haemostasis and impact of fibrinogen supplementation on clot properties using global haemostasis assays in patients on chronic dialysis.

Backgorund: Multifactorial haemostasis disorders are typical of patients with end-stage renal disease (ESRD) on chronic haemodialysis (HD). Thromboelastometry and impedance aggregometry allow for a comprehensive assessment of clot formation, lysis, and platelet (PLT) function. This study aims to determine the haemostatic profile in a group of patients with ESRD on chronic, interrupted dialysis, especially in terms of PLT function and the impact of fibrinogen concentrate supplementation on clot properties.

Transversus abdominis plane block versus quadratus lumborum block type 2 for analgesia in renal transplantation: A randomised trial.

Background: Several studies have shown an analgesic efficacy of a transversus abdominis plane block (TAPB) in reducing opioid requirements during and after cadaveric renal transplantation surgery, but the effect of a quadratus lumborum block (QLB) in this type of surgery is unclear.

Objectives: The main objective of this prospective, randomised, double-centre clinical study was to compare the analgesic efficacy of a one-sided lateral approach TAPB with a unilateral QLB type 2 in cadaveric renal transplantation surgery.

Design: Randomised, single-blinded trial.

[Copeptin - a novel biomarker for perioperative homeostasis disorders].

Recently there has been an increasing amount of research on copeptin as a novel biomarker for stress response and homeostasis disorders in a wide spectrum of morbidities. Copeptin is a stable and easily measured surrogate marker of arginine vasopressin and is increasingly included as a part of routine patient assessment tests in selected clinical scenarios. Such tests are also performed in the perioperative period, in which complication risk assessment is of exceptional importance.
