Filter by:The primary aim of this study is to assess the efficacy of post-operatory HFNC in reducing the incidence of hypoxemia after gynecological oncology surgery, compared to the standard application of O2 through a Venturi mask; The secondary objectives are to investigate the occurrence and entity of lung atelectasis, to evaluate diaphragmatic function and respiratory discomfort, and to evaluate the incidence of respiratory complications after seven days in the two groups. Patients will be randomized into two groups: HFNC and Control. The patients will be studied with preoperative lung and diaphragmatic ultrasound. Standard general anesthesia will be administered in the two groups. Ultrasound will be performed at arrival in the recovery room (RR) and before discharge from the RR. In the HFNC group, high-flow O2 will be administered; in the control group standard O2 therapy with Venturi mask will be administered. Arterial blood gas analysis upon arrival in the RR and after two hours of O2 therapy in both groups will be checked. The incidence of post-operative respiratory complications will be monitored in the seven days following surgery.
Rib fractures are one of the most common injuries in trauma patients. These fractures are associated with significant pain as well as decreased ability to inspire deeply or cough to clear secretions, which together lead to complications of the lungs and breathing which leads to risks of further injury and even death. One recent study found that the ability to move air into and out of the lungs practically doubled with the administration of a single-injection Erector Spainae Plane Block (ESPB) while pain levels nearly halved. However, a single-injection nerve block lasts less than 24 hours while a perineural local anesthetic infusion (also termed a "continuous peripheral nerve block") may be administered for multiple days. This entails inserting a tiny tube through the skin and into the area around the nerves, after which more local anesthetic may be administered prolonging the numbing effects. The possibility of extending the duration of a ESPB with local anesthetic administration via a perineural catheter has not be investigated. We therefore are conducting a randomized, triple-masked, placebo-controlled, parallel-arm study to investigate the addition of a continuous ESPB to a single-injection ESPB following traumatic rib fractures. The primary outcome of this study will be the maximum inspired volume measured by incentive spirometry on the afternoon following the nerve block procedure. We hypothesize that the maximum inspired volume will be significantly increased in the afternoon following the procedure with the addition of a continuous ESPB to a single-injection ESPB.
Laparoscopic nephrectomy is a surgical technique to excise a diseased kidney. It's a minimally invasive technique, so when compared to open surgery, it can mean significantly less post-operative pain, shorter hospital stay, earlier return to work and daily life activities, a more favourable cosmetic result and outcomes similar to that of open surgery. Recently, advanced laparoscopic surgery has targeted older and high risk patients for general anesthesia; in these patients, regional anesthesia offers several advantages with improved patient satisfaction. Compared with alternative anesthetic techniques, epidural anesthesia may reduce the risks of venous thromboembolism, myocardial infarction, bleeding complications, pneumonia, respiratory depression and renal failure. The aim of this study is to compare the conventional general anesthetic technique to the regional anesthesia for laparoscopic nephrectomy, in modified lateral decubitus position using low-pressure pneumoperitoneum.
Anaesthesia or sedation for dental surgery is Challenging. Over-sedation, leading to upper airway obstruction, desaturation and apnoea, is very common. On the other hand, it is also very common that inadequate sedative drugs were given, leading to under-sedation with unsatisfactory experience during operation. Therefore, it is good if some other methods are provided for sedation, avoiding side effects associated with sedative drugs.
Regional anesthesia and analgesia may maintain immune function, reduce surgical stress, and also reduce volatile anesthetics and opioids requirements. Local anesthetic drugs used in regional anesthesia and analgesia work to have anti-proliferative and cytotoxic effects on cancer cells. Pro-inflammatory cytokines such as IL-1, IL-6, and TNF-alpha increase in levels in peripheral nerves, spinal cord, brain (brain stem, locus sereleus, thalamus, hippocampus, and prefrontal cortex) after peripheral nerves are injured. The anti-inflammatory cytokine IL-10 is decreased in levels after peripheral nerve injury. The balance between pro-inflammatory and anti-inflammatory cytokines affects the severity of pain.
Participants under general anesthesia will be randomly treated with an adjusted dose dopamine or norepinephrine to elevate 10% of mean arterial pressure. Systemic hemodynamic data is recorded by PRAM and the change of cardiac index is compared between groups.
Prospective randomized controlled trial to determine if opioid-free anesthetic for tonsillectomy is non-inferior to standard opioid-containing anesthetic
To date, there have been no studies done relating serum cortisol levels and intranasal dexmedetomidine sedation. However, there was a behavioral study done on pediatric patients confirming reduction serum cortisol levels with perioperative dialogue intervention.There have been a number of studies done on adult patients indicating that dexmedetomidine was indeed capable of reducing level of anxiety with evidence of lower serum cortisol levels. Hence, we postulated that intranasal dexmedetomidine administration in pediatric patients will lower the serum cortisol levels but we need to evaluate the extent of reduction.
Different modality of anesthesia and analgesia could influence a postoperative quality of recovery (QoR). This study is exploring early QoR after unilateral nephrectomy in the two groups of anesthesia. The first group had a light general anesthesia with thoracic epidural anesthesia and postoperative epidural analgesia with morphine and ropivacaine. The second group had general anesthesia and a continuous postoperative analgesia with tramadol. The postoperative QoR was evaluated 24 hours after surgery.
An algorithm to calculate hemodynamic parameters based on blood pressure waveform was developed by collecting arterial blood pressure of patients during surgery
