NCT ID: NCT06040307 Completed - Pain, Postoperative Clinical Trials

Guiding Opioid Administration in Patients With Regional Anesthesia

GORA
Start date: December 18, 2023
Phase: N/A
Study type: Interventional

General anesthesia is a combination of hypnotic drugs to achieve unconsciousness and opioid analgesics to ensure antinociception. An alternative approach to the intraoperative administration of high potency opioids in order to achieve antinociception during surgery is combining a general anesthesia with a regional anesthesia. Modern general anesthesia aims to treat nociception induced by surgical stimulation while avoiding an overdose of opioid analgesics and reducing side-effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In the current clinical practice, the opioid dosage is usually chosen by clinical judgment. Recently different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. One of the first commercially available nociception indices was the Surgical Pleth Index (SPI) derived by the CARESCAPEā„¢B650 patient monitor (GE Healthcare). Until today, it remains unknown whether guiding sufentanil administration by SPI monitoring affects the administered amount of intraoperative and postoperative opioid, immediate postoperative pain in the postanesthesia care unit (PACU) and the quality of postoperative recovery in patients with a combination of general and regional anesthesia. This study aims to investigate whether guiding sufentanil administration by SPI monitoring - compared to routine care - reduces intraoperative sufentanil consumption in patients having trauma and orthopaedic surgery with a combination of general and regional anesthesia.

NCT ID: NCT05063227 Completed - Pain, Postoperative Clinical Trials

Prediction of Postoperative Pain by Nociception Monitoring

PredictPain
Start date: October 6, 2021
Phase:
Study type: Observational

General anesthesia is a combination of hypnotic drugs and opioid analgesics. Modern general anesthesia aims to treat nociception induced by surgical stimulation while avoiding an overdose of opioid analgesics and reducing side-effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In the current clinical practice, the opioid dosage is usually chosen by clinical judgment, though recently different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. Nevertheless, the impact of nociception-monitor-guided opioid administration on the administered amount of opioid, postoperative short-term recovery, and long-term outcome is inconclusive. This study aims to investigate the predictive power of different nociception monitoring systems for the prediction of moderate to severe immediate postoperative pain from nociception indices measured before awakening from general anesthesia.

NCT ID: NCT04587505 Completed - Quality of Life Clinical Trials

Effect of Epidural Anesthesia and Analgesia on Quality of Recovery After Radical Prostatectomy.

QoR
Start date: April 1, 2019
Phase: Phase 4
Study type: Interventional

Postoperative quality of recovery (QoR) could be related to anesthesia and postoperative analgesia. This study is exploring early QoR after radical prostatectomy in the two groups of anesthesia. The first group had a light general anesthesia with lumbal 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.

NCT ID: NCT04581720 Completed - Anesthesia Clinical Trials

Minimum Current for Train-of-four Monitoring

Start date: October 12, 2020
Phase: N/A
Study type: Interventional

Neuromuscular monitoring during general anesthesia is important to make sure adequate muscle relaxation during operation and adequate recovery of muscle power and spontaneous breathing during emergence from general anesthesia. The neuromuscular monitoring is usually using electrical stimulants and the method called train-of-four (TOF) is representative. Because it uses electrical stimulants, the patients could be uncomfortable and feel pain during the monitoring when the patients are conscious. Lowering the current of the stimulants would be helpful in reducing the pain, but there is a concern that the TOF results performed in lower current would be underestimated or inaccurate. Therefore, the investigators want to find the minimal current for TOF monitoring that shows adequate TOF results.

NCT ID: NCT04521556 Completed - Quality of Life Clinical Trials

Effect of Epidural Anesthesia and Analgesia on Quality of Recovery After Unilateral Nephrectomy.

QoR
Start date: April 1, 2019
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT04188314 Completed - Quality of Recovery Clinical Trials

Comparing Quality of Recovery Between Desflurane & Isoflurane in Eye Surgery Patients at Dr George Mukhari Acad Hospital

DIQoR
Start date: February 20, 2020
Phase: N/A
Study type: Interventional

Recovery after surgery and anaesthesia has traditionally been assessed with objective measures including time to awakening, time to regaining airway reflexes, duration of stay in the recovery room and/or hospital, and incidence of adverse events like pain and post-operative nausea and vomiting. Increasingly, the patient's experience of their post-operative recovery is being recognised as an important outcome after surgery. The 15-Item Quality of Recovery score (QoR-15) has been validated to give a patient-centred global measure of overall health status after surgery and anaesthesia. This score has recently been translated and validated in isiZulu. Desflurane is the newest anaesthetic vapour to market, with many benefits from the anaesthetist's perspective: faster time to awakening, faster time to regaining airway reflexes, and a clearer sensorium post-operatively. However, there is a paucity of data evaluating whether this translates to better quality of recovery for the patient. Desflurane is more expensive than other volatiles; for economic use, it is recommended to use Desflurane with a low flow (up to 2L) anaesthetic technique. Isoflurane is the most commonly used volatile anaesthetic agent at Dr. George Mukhari Academic Hospital. Concerns about the increased cost of desflurane compared to isoflurane limits the use of this novel agent in the public sector in South Africa. Following an extensive literature review, no studies could be found comparing quality of recovery between desflurane and isoflurane using a validated quality of recovery tool like the QoR-15. The research question in this study is whether there is a clinically significant difference in post-operative quality of recovery (using the QoR-15 score) between desflurane and isoflurane inhalational anaesthesia in adult patients presenting for elective ophthalmological surgery under general anaesthesia. This study will therefore compare quality of recovery between desflurane and isoflurane inhalational anaesthesia. Furthermore, the study will evaluate the relative cost of using either volatile with a basal flow anaesthetic technique.

NCT ID: NCT04069169 Completed - Clinical trials for Scoliosis; Adolescence

IV Lidocaine Analgesia in Pediatric Scoliosis Surgery

P-IVLT
Start date: December 18, 2019
Phase: Phase 3
Study type: Interventional

Surgical correction of scoliosis in children is a long procedure, with an equivalently long recovery time, that is commonly performed at BC Children's Hospital. Treating pain immediately after the procedure is a priority for children during recovery. Morphine is one medication that can be used to manage post-operative pain, but unfortunately, its use is accompanied by a number of side effects which can affect recovery. These include nausea, vomiting, pruritus, sedation, dysphoria, respiratory depression, constipation, ileus, and urinary retention. In order to control pain and reduce morphine consumption, intravenous lidocaine is being investigated. This therapy has been beneficial in adult populations undergoing abdominal surgery and has been associated with decreased post-operative pain, decrease use of opioids including morphine, and ileus. These all contribute to shorter lengths of stay in the hospital and better recovery in the adult population. Intravenous lidocaine is used by some anesthesiologists at BC Children's Hospital to manage post-operative pain in children receiving surgical correction for scoliosis, but this is not a standard of practice. We now propose to conduct a double-blind randomized controlled trial to determine if intravenous lidocaine, infused from start of anesthesia up to 48 hours post-operatively, will reduce morphine use and improve post-operative pain in the pediatric population.

NCT ID: NCT03420586 Completed - Anesthesia, General Clinical Trials

Nitrous Oxide Added at the End of Sevoflurane Anesthesia and Recovery

SEVONATE
Start date: February 7, 2018
Phase: N/A
Study type: Interventional

Addition of nitrous oxide N2O towards the end of prolonged isoflurane anesthesia hastens patients recovery. The hypothesis is that the addition of N2O at the end of prolonged sevoflurane anaesthesia also hastens early recovery without increasing the frequencies and intensity of PONV and improves quality of recovery.

NCT ID: NCT03131258 Completed - Anxiety Clinical Trials

The Effects of Pre-operative Anxiety on Anesthetic Recovery and Post-operative Pain in Donor Nephrectomy

Start date: June 2014
Phase: N/A
Study type: Interventional

Kidney transplant is the most effective choice of treatment for patients with end-stage kidney failure in terms of quality of life and longevity. Today, 20-25% of kidney transplantations are implemented with living donors. Donor nephrectomy is an operations which has the end goal of a living donor donating one of his kidneys to a patient with end-stage kidney failure (1). Pre-operative anxiety is a condition which is characterized by a random illness, being hospitalised, anesthesia, surgery, or uneasiness or anxiety stemming from not knowing what is to be experienced. Educating and informing in the pre-operative period is the first step in mentally preparing the patient for the operation. In some studies, it has been pointed out that patients who were thoroughly informed in the pre-operative period have lower anxiety levels both in the pre-operative and post-operative periods with also less levels of pain and increased recovery rates in the latter (2). Anesthetic recovery starts at the end of the surgical process and ends with the anesthetized patient completely regaining a wide-awake, responsive state, defensive reflex, and muscle strength. Post-operative pain is acute pain which starts with surgical trauma and ends with tissue healing (3). Providing optimal post-operative analgesia plays an important role in the prevention of post-operative complications (1,4,5). There are studies which examine the link between pre-operative anxiety and post-operative pain (59,74,74,77,78). Patients who will undergo a donor nephrectomy constitute a specific group of patients both because they are not operated due to a health problem that they have and because the operation results with them losing an organ. There are no prospective studies about the effects of pre-operative anxiety on anesthetic recovery and post-operative pain in individuals who have undergone donor nephrectomy in literature. Because of this, we have aimed to research prospectively the effects of pre-operative anxiety on anesthetic recovery and post-operative pain in patients that were to undergo donor nephrectomy surgery.

NCT ID: NCT03034577 Completed - Laparoscopy Clinical Trials

Deep Neuromuscular Block for Laparoscopic Surgery

DEEPBLOCK
Start date: June 16, 2017
Phase: Phase 4
Study type: Interventional

Trial summary: deep neuromuscular block is proposed as a technique to improve operative conditions for laparoscopy. Early clinical data would suggest that there may also be patient benefits beyond the operative period related to lower intra-abdominal pressure, and improved surgical exposure. In order to safely conduct deep neuromuscular blockade, it is essential to use Sugammadex to reverse the neuromuscular block. Conventional practice is to provide moderate neuromuscular block and reverse with neostigmine. It is not possible to safely reverse deep neuromuscular block using neostogmine, as the majority of block must have worn off for neostigmine to be effective. in order to identify whether deep neuromuscular block improves quality of recovery after surgery, the investigators will conduct a randomised trial of deep versus moderate neuromuscular block, whilst minimising variance in other anaesthetic techniques and drugs used. the outcome measured will be the post-operative quality of recovery over multiple time periods using the Postoperative Quality of Recovery Scale (PostopQRS). 350 patients will be enrolled over 4 centres.
