Pre-oxygenation increases oxygen reserves in the body to reduce the likelihood of oxygen desaturation on induction of general anaesthesia. Pre-oxygenation with facemask is the commonest method method of pre-oxygenation. High-flow nasal oxygen is a newer alternative. This study randomises participants to receive pre-oxygenation by one of three methods: facemask, high-flow nasal oxygen, high-flow nasal oxygen plus mouthpiece.
The goal of the research is to define clinically relevant molecular markers for increased risk of peri-/ postoperative organo-dysfunctions, inflammation, adverse events and disease progression. To better understand the perioperative impact the investigators aim to determine perioperative levels of molecular markers over time in the available samples and clinical data of the Bern perioperative Biobank (BPBB) cohort to finally increase quality of perioperative care of patients by permitting preventive measures to be taken early in patients at risk.
The objective of this study is to pilot an opioid free anesthetic protocol for patients undergoing total hip replacement.
This is a prospective, multi-center, non-invasive, interventional, data collection study to improve the current BIS algorithm in the elderly adult population.
Many clinicians continue to rely on subjective evaluation in making decisions about the adequacy of neuromuscular function before tracheal extubation rather than using quantitative monitoring. The aim was to compare the sugammadex dose as suggested by senior anaesthesiologists (SSD) based on clinical experience versus the dose determined by quantitative monitoring (QSD) to determine if the subjective dose was appropriate.
To evaluate the success of surgical anesthesia of lateral and medial approaches of the costoclavicular block in patients undergoing upper extremity surgery.
After reaching 1 MAC level with 4 lt / min fresh gas flow and 2.5% sevoflurane concentration in the initial stage in 35 patients, anesthesia maintenance will be continued with 0.5 lt / min fresh gas flow and 2 -4% sevoflurane concentration with the target of 1 MAC. For 35 patients, after reaching 1 (MAC) level with 1 lt / min fresh gas flow and 8% sevoflurane concentration in the initial phase, maintenance of anesthesia will be continued with 0.5 lt / min fresh gas flow and 2 -4% sevoflurane concentration, targeting 1 MAC.
The use of intravenous lidocaine in continuous infusion in the perioperative period is associated with a reduction in postoperative pain scores, opioid use, incidence of nausea and vomiting, among other favorable outcomes. However, this therapeutic intervention has not yet been adequately evaluated by clinical trials when associated with regional anesthesia. The aim of this study is to evaluate whether the use of intravenous lidocaine in continuous infusion during spinal anesthesia with isobaric bupivacaine alters the time to regression of sensory block in patients undergoing surgical procedures for the treatment of bone and connective tissue tumor surgeries. This will be a triple-blind randomized trial. The sample size estimated was 66 patients. The study will include all patients who meet the pre-established inclusion and exclusion criteria, choose to participate, and agree with the Informed Consent Form. The main anesthetic technique will be spinal anesthesia with 13 mg of isobaric bupivacaine. Patients will be allocated in two groups in a blindly after randomization: Group S (lidocaine 0.75mg.kg-1 in bolus followed by infusion of saline solution) and Group L (lidocaine 1.5 mg.kg-1 followed by continuous infusion of lidocaine solution at 2 mg.kg-1.h-1). The primary outcome will be the time to T12 regression of the sensory block. Will also be evaluated: time to regression of the motor block, most rostral dermatome achieved by the sensory block, time to two-segment regression oh the sensory block, propofol dose in the operating room, postoperative pain score at rest, pain at movement score, quality of recovery, use of opioids in the postoperative period, nausea or vomiting, dizziness, shivering, arrhythmias, hypotension, urinary retention, and length of stay. The records will be assigned to the RedCap database. The data will be extracted without identification of the allocation groups for the R software and the groups will be revealed to the researcher after the end of the statistical analysis to write the summary of the results. The results will be submitted to scientific journals afterward.
Recently, a lot of side effects have been identified from the perioperative use of opioids. To remedy this, anesthesia research has recently focused on providing safe general anesthesia without opioids in a new concept or anesthetic technic called Opiod Free Anesthesia (OFA). Evidence on the effectiveness and safety of OFA is scarce in Africa, with no report from Cameroon.The aim of this study is to demonstrate the feasibility of an adapted OFA protocol as well as its efficacy and safety in very painful surgeries like gynaecology surgery in a low-resource setting.
