The Metabolic and Bariatric Surgery Chapter of the Association of Polish Surgeons (Polish acronym: SCMiB TCHP) is a Polish specialist scientific society representing bariatric surgeons as well as specialists from other disciplines and professions cooperating with them during the provision of services in the field of bariatric and metabolic surgery, as well as the entire care process before and after surgery. The following standards constitute the minimum requirements set by the SCMiB TCHP for good practice of the basic process of bariatric care throughout its entire period, which ensure satisfactory safety and effectiveness of the obesity treatment and its metabolic complications.
Background: The effect of etomidate administration on the adrenal cortex in obese patients is still unclear. The objective of the study was to determine the influence of a single dose of etomidate on cortisol secretion in the morbidly obese. Methods: 127 healthy patients were enrolled into the study. Data from 82 patients scheduled for elective laparoscopic surgery were analyzed. 62 of them were morbidly obese, while 20 had normal body mass. The participants were divided equally into etomidate and thiopental groups, depending on the kind of intravenous anaesthetic used for the induction of anaesthesia. Each patient's serum cortisol concentration was measured five times: on the day before surgery (sample A), two hours after the induction of anaesthesia (sample B), after a short tetracosactide test (sample C), 24 hours after the induction of anaesthesia (sample D), and after a second short stimulation test (sample E).
Results:The mean cortisol concentration in obese patients in the etomidate group was lower two hours after the induction of anaesthesia (sample B, P < 0.001), and 30 minutes after the first tetracosactide test (sample C, P < 0.001) compared to obese patients in the thiopental group. There were no differences between the groups in sample A (P = 0.833), D (P = 0.614) and E (P = 0.769). We found no changes in haemodynamic parameters between both groups. Conclusions: Etomidate decreased serum cortisol concentration and decreased reactivity to tetracosactide both in morbidly obese and in normal weight patients. This effect was reversible within 24 hours.
Thoracic paravertebral block is the technique of injecting local anesthetic adjacent to the thoracic vertebra close to where the spinal nerves emerge from the intervertebral foramina. It is effective in treating acute and chronic pain of unilateral origin from the chest and abdomen. This technique causes pain relief with pulmonary function preservation and great hemodynamic stability. 66 year old woman (156 cm, 80 kg, BMI 32) with chronic right heart failure, hypertension and obesity, on chronic oxygen therapy was presented for elective mastectomy due to breast cancer. She suffered from severe COPD and also bullous emphysema. FVC 1.59 l; FEV1 0.55 l; FEV1%FVC 34.6. The paravertebral block was performed using the multi-shot percutaneous technique with additional light general anesthesia. For confirmation, of proper analgesia range, control of temperature changes, using FLIR i7 infrared camera, was performed. Control photos were made 20 min after the blockade and then 10 min later. Infrared photo showed rise of temperature reading in every marked region. There were no hemodynamic and pulmonary complications postoperatively. Paravertebral block in combination with sedation creates excellent conditions for breast surgery procedures. Additional temperature changes monitoring performed with infrared camera may confirm proper range of analgesia needed to perform surgery. Great cardiovascular stability and very good pulmonary function preservation make this method excellent for high risk patients. Low complication rate is additional advantage. In our opinion this method is recommendable.
Vaccine-induced immune thrombotic thrombocytopenia (VITT) with cerebral venous sinus thrombosis (CVST) has been recently reported after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a patient with fulminant CVST and thrombocytopenia after receiving the ChAdOx1 nCoV-19 vaccine. Although the patient received immediate anticoagulant and intravenous immune globulin treatment, he died within 24 h after hospital admission. VITT and CVST are rare conditions; however, the course may be fatal. Therefore, clinicians should be familiarized with the clinical and laboratory features of VITT.
There was a relationship between bone cement implantation during primary hip arthroplasty and elevated S100B protein plasma concentration during the short postoperative period, but the results of the neuropsychological tests did not reflect this.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
