Filter by:The Erector Spinal Block (ESP) is based on the deposition of the local anesthetic in the inter-fascial space between the dorsal extensor muscle and the intercostal muscles at the height of the transverse processes. The scope of the blockade covers the dorsal and ventral branches of the thoracic spinal nerves, but also in most cases the investigetors are able to obtain a wide distribution of the drug into the paravertebral space by "permeating" the local anesthetic through the fascial compartments. The clinical effect of the blockade is due to blocking the nerve structures of the paravertebral space (spinal nerve branches and the sympathetic trunk). The scope of the blockade, after its execution at the level of Th5, most often includes the segments from Th1 to L1. Lidocaine used in intravenous infusion is one of the recommended components of multidirectional analgesia. Its adjuvant properties make it possible to reduce the amount of opioid drugs used, and thus - to reduce the frequency of their side effects. The aim of the study is to test the effectiveness and safety of the use of lidocaine infusion or Erector Spinal Block in multimodal analgesic management.
Emergence agitation, defined as restlessness, disorientation, arousal, and/or inconsolable crying, is a common phenomenon seen in the early phase of recovery from general anesthesia; this may cause respiratory depression, nausea and vomiting, as well as an increase in blood pressure, heart rate and myocardial oxygen consumption. Although its pathogenesis remains unclear, ENT (ear, nose and throat) surgical procedures have been reported to have a higher incidence of agitation in both adults and children. In recent years, low-flow inhalation anesthesia has been widely used in adult anesthesia practice. The aim of this study is to compare the effects of low flow anesthesia and normal flow anesthesia on emergence agitation.
Gastroenteroscopy diagnosis and treatment drugs need to meet the needs of quick onset, quick recovery and less anesthesia complications. Remimazolam is an anesthetic sedative independently developed by China. It is a new short-acting GABA(A) receptor agonist. Remimazolam has the advantages of rapid onset, rapid recovery, antagonist, controllable degree of cardiovascular and respiratory depression, low incidence of hypotension and respiratory depression. However, elderly patients as important and special patients, there are still a lack of relevant studies and reports. In order to verify the safety and effectiveness of remimazolam in the gastroenteroscopy treatment of elderly patients, it can reduce the incidence of intraoperative hypotension or respiratory depression rate, improve the quality of recovery of elderly patients.
The satisfactory recovery of the patient after a surgery with an anesthetic request is very important for a quality and excellence assistance. The quality of recovery questionnaire QoR-15 was validated by their authors in 2013 with the study titled development and psychometric evaluation of a postoperative quality of recovery score: the QoR-15. This questionnaire allows a comprehensive assessment by associating the physiological parameters until then assessed with the subjective personal perception of the patient of his state of health. With the consent of its original author, this study is carried out to validate the questionnaire in Spanish and adapted to our environment.
Abdominal wall blocks are frequently used as part of multimodal analgesia for pain control after abdominal surgery. There are studies using the Transversus Abdominis Plane Block for postoperative pain control in laparoscopic cholecystectomies. In this study, the investigators aimed to compare the advantages of these two methods by applying the Transversus Abdominis Plan Block for postoperative pain control after laparoscopic cholecystectomy with the help of postoperative USG and laparoscopy during surgery.In this study, the investigators aimed to compare the advantages of these two methods by applying the Transversus Abdominis Plan Block for postoperative pain control after laparoscopic cholecystectomy with the help of postoperative USG and LAPAROSCOPY during surgery.
Muscle relaxants are routinely applied during anesthesia to facilitate endotracheal intubation and to improve surgical working conditions. Several investigations have shown that a deep neuromuscular block (NMB) improves the surgical working conditions over a moderate NMB and effectively precludes sudden deterioration of the surgical field. However, whether the improvement of surgical working conditions translates into less intra- and postoperative complications remains uncertain. Small prospective or retrospective studies shown an decrease of the incidence of intraoperative adverse events and postoperative complications after a deep NMB. There is a need to confirm these outcome data prospectively, in a large number of patients and clinics and during a variety of surgical procedures.
Co-administration of propofol and remifentanil is considered to be an ideal total intravenous anesthesia technique, which is widely used in induction and maintenance of general anesthesia. Remifentanil and propofol can be mixed in polypropylene syringes for one hour with a remaining concentration of 91% in small concentrations of remifentanil. However, delivery of remifentanil-propofol mixture by target-controlled infusion(TCI) for general anesthesia in surgical procedure has not been described. Breast cancer surgery ( including modified radical mastectomy and breast-conserving surgery) is a less time-consuming procedure for patients with breast cancer with one-hour duration in our hospital. This pilot study was to examine the merit of remifentanil-propofol mixture as a GA regimen for breast cancer surgery.
Target controlled infusion with remifentanil is widely used during cardiac surgery, wich is performed using the Minto model. It was derived from patients undergoing general surgery. However, pharmacokinetics of remifentanil can be changed during cardiopulmonary bypass. The investigators tested whether Minto model for target controlled infusion produces constant plasma remifentanil concentration during the cardiac surgery.
The overall aim with this project is to investigate the effect of dexmedetomidine on control of breathing in healthy volunteers and to compare it with propofol at the same degree of sedation.
The aim of this study is to determine whether induction of anesthesia with thiopental followed by propofol infusion is able to maintain sufficient depth of anesthesia .
