Comparative study on efficacy of haemostatic therapy guided either by standard laboratory coagulation parameters or point-of-care testing in patients undergoing vascular surgical procedures. We investigate the amount of perioperative bleeding and the number of blood product used. Inclusion criteria Patients scheduled for elective and acute open aorta surgery or undergoing acute aorta surgery with minimally invasive techniques and were provided treatment in the operating theatre and/or ICU attached to perioperative care, they must be at least 18 years of age and written informed consent was obtained from the patient or his/her legal representative. Randomisation technique Patients will be randomly assigned to each of two treatment groups using sealed envelopes. In group 1 (G1) haemostasis strategy guided by conventional coagulation tests, while in group 2 (G2) transfusion algorithms guided by point-of-care (POC) tests will be carried out. Sampling techniques and measurements For assessment of monitored parameters shall be used arterial or venous blood depending on the catheter placed preoperatively. In case of the above mentioned vascular surgical procedures, all patients will receive arterial cannula routinely, and, depending on the extension of procedure, as appropriate, a central venous catheter will be inserted as well. Sampling in the patient groups shall be performed as follows: - pre- and postoperative evaluation of standard laboratory parameters in all patients - evaluation of standard laboratory parameters and arterial Astrup test during and after surgery in group 1, if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes - in case of elective surgery: thromboelastometry and arterial Astrup test during and after surgery in group 2 if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes - in case of acute surgery: thromboelastometry and arterial Astrup test before, during and after surgery in group 2 - in case of positive anamnesis, preoperative platelet aggregation test in both groups Besides the above samplings, routine lab tests (blood gas, blood count, sodium (Na), potassium (K), parameters of renal and liver function, clotting and inflammation, lactic acid, blood sugar) will be performed every day as usual during intensive therapy.
In september 2017 audio recording during laparoscopic general surgery was implemented as routine a Lindesbergs hospital. The study was designed to observe operations before and after the introduction of audio recording. The main outcome of the study was time spent on non-relevant conversation.
Major adverse cardiac events (MACE) are a leading cause of mortality in patients undergoing noncardiac surgery. Patients with perioperative myocardial injury (PMI), defined as either myocardial infarction and lower elevations in cardiac troponin, are also at substantially increased risk of additional cardiac and noncardiac complications. Accordingly, it is plausible to assume that PMI negatively affects quality of life in terms of disability. The aim of this study is to investigate and compare the independent prognostic effects of the different PMI phenotypes (myocardial infarction and non-infarct troponin elevations) and noncardiac complications on disability in patients undergoing elective noncardiac surgery.
Background: Several randomized clinical trials have shown beneficial effects of pre-operative glucocorticoids on post-operative complications. Studies on the effects of glucocorticoids on the postoperative recovery after liver-resection show significantly lower markers of infection and liver damage, and some studies have shown a shorter hospital stay. Studies on the effects in the immediate postoperative phase are lacking. Methods: Randomized, double-blind, controlled trial evaluating incidence of postoperative complications in the immediate postoperative phase (and during admission) after open liver surgery. Participants are randomized to either active treatment (methylprednisolone 10 mg/kg) or control (8 mg dexamethasone), administered just prior to surgery. All patients undergoing open liver resection at our institution are eligible. Included patients are stratified according to extent of surgery into minor (<3 segments) or major (≥3 segments) group. Patients in major group participate in Substudy I (markers of endothelial damage). Patients operated between January and July 2018 participate in Substudy II (delirium).
The operation of the lower third molars is one of the most common oral surgery procedures in the world. The surgery is mostly done in local anesthesia which makes the surgery as pleasant as possible for the patient. In addition to anesthesia control, it is also extremely important to insure postoperative pain control since that is the nuisance that patients are most likely to complain about after oral surgery. It has been noticed that magnesium added to local anesthetics can improve and prolong its effect, but also reduce postoperative pain and accelerate recovery. It can also be used as an auxiliary to control pain and inflammation, which is why we will use it in this study, because we have not been able to find magnesium data in the literature for the removal of the lower third molars. Studies that have already been conducted with oral magnesium are for the purpose of preventing asthma, migraine, for reducing mood swings in PMS, reducing pain after endotracheal intubation, and many others. Removal by using operative procedure is the only way to remove lower third molars. The main objective of the study is to demonstrate the influence of the orally received magnesium citrate (before and after surgical removal of the lower third molar) on the quality and duration of the anesthetic block and also its effect on postoperative pain control. Other specific objectives are to investigate the effect of pre/postoperatively received magnesium on: 1. swelling stage after surgery. 2. time occurrence and duration of anesthesia. 3. trismus stage after the operative procedure. 4. the total amount of analgetics taken after surgery Benefits for the respondents will be in the assumption that the anesthetic block of the mandibular nerve will last longer with better quality, thus making the surgical procedure more pleasant and that the overall postoperative pain will be lessened and recovery faster in the magnesium citrate group. We also assume that in the magnesium citrate group trismus will be less pronounced and that swelling in postoperative days will be smaller.
Perioperative anaphylaxis is associated with significant morbidity and mortality. Most textbooks describe it as a rare event of the order of 1 in 10 to 1 in 20,000 general anaesthetic cases. However, a recent study in the United Kingdom suggested that 1 in 350 cases have features suspicious of perioperative anaphylaxis. This study suggests that perioperative anaphylaxis may be under recognised and under reported. When perioperative anaphylaxis is recognised, it would be ideal to carry out investigations firstly to confirm the diagnosis of anaphylaxis and secondly to identify the causative agent. The latter can be difficult in the context of anaesthesia where the patient is exposed to several drugs and other reagents in a short space of time. One of the interesting aspects of perioperative anaphylaxis is that there is variability in its epidemiology between different countries, for example between the United Kingdom, France, Scandinavia and Australia and New Zealand. There are currently no data from Egypt to include in such comparisons and to inform clinical practice. As well as being at risk if a drug allergen is not identified, patients can also be at risk from an incorrect allergy label. The most common example of this is penicillin allergy where fewer than 10% of patients with a history of penicillin allergy are found to be allergic. Incorrect penicillin allergy labels are potentially harmful for patients attending for surgery because the label independently increases the risk of developing infection to resistant organisms, longer hospital stays and mortality.
Frailty is prevalent in older adults and may be a better predictor of post-operative morbidity and mortality than chronological age. Preoperative risk factors and physiological reserves were assessed on patients more than 70 years old who are scheduled for surgery under general or regional anesthesia. The aim of this retrospective analysis was to examine the impact of relevant geriatric assessments on adverse outcomes in older surgical patients.
The purpose of this study was to identify the major complications and their risk factors of elderly patients who had undergone Hemi-hip Arthroplasty.
Postoperative gastroesophageal reflux is one of the most common complications of distal gastrectomy. With more attention paid on it by surgeons, several new operation methods have been practised. Among all these, distal gastrctomy with Billroth II + Braun anastomosis was reported to be an useful method to decrease postoperative reflux rate. Meanwhile, the direction of anastomotic peristalsis has also been reported to affect the anastomosis and thus make difference in reflux rate. We design this study to investigate the potential effect and the superiority of antiperistaltic vs isoperistaltic Billroth II + Braun reconstruction in distal gastrectomy.
