Filter by:Total arthroplasty surgery of the shoulder is performed under general anesthesia. Pain control for after the surgery can be achieved purely with intravenous and oral pain medication or in combination with freezing of the nerves. Nerve freezing (nerve block) placed before surgery has the potential to substantially reduce the amount of inhaled anesthetic given to the patient during surgery. This can benefit the patient by minimizing the opioid usage after surgery and also reduce cost to the system in terms of duration of hospital stay. The purpose of the study is to investigate whether the inclusion of a nerve block to the general anesthetic for total shoulder arthroplasty surgery will also reduce the amount of inhaled anesthetic and thereby lowering the environmental footprint from the anesthetic. The investigators of the proposed study plan to quantify the amount of inhaled anesthetic used for each case and will compare how the consumption is affected by whether the nerve block is applied before or after surgery. Patients will have a nerve block catheter (interscalene catheter) placed under ultrasound-guidance prior to the induction of general anesthetic by an experienced regional anesthesiologist. The nerve block catheter will be bolused with a solution to which the anesthesiologist is blinded which will either be local anesthetic or normal saline (sham). The general anesthetic will be conducted according to a the protocol with the aim of maintaining a standard anesthetic depth monitored by patient state index (PSI). Measurements of the MAC-Value (minimum alveolar concentration) of inhaled anesthetic will be recorded every five minutes and the total amount of volatile anesthetic (in ml and ml/kg) will be noted down by a blinded observer. At the end of the case the anesthesiologist blinded to the solution will inject another solution (now a saline (sham) or local anesthetic before the patient is woken up.
This study evaluates differences in how administering liposomal bupivacaine via two different methods affects postoperative pain control in laparoscopic abdominal surgery patients. Half the participants will receive liposomal bupivacaine via a transverses abdominis plane block while the other half will receive liposomal bupivacaine via local infiltration.
In this study to planned to research the efficacy of low-flow anesthesia on patients undergoing sleeve gastrectomy due to morbid obesity on respiratory functions after surgery by examining FEV1 and FVC values and FEV1/FVC ratio.
The non-intubated video-assisted thoracic surgery (NIVATS) can avoid intubation-related complications and for a smoother postoperative recovery. Successful results are accumulating not only from anecdotal case reports of difficult and high-risk patients not suitable for an intubated general anesthesia. However, in spite of safety and feasibility, there were still three main concerns: 1. how to maintain spontaneous breathing with optimal anesthetic depth; 2. How to analyze the components of general anesthesia and regional anesthesia; 3.what's the benefits on the recovery and the risk of aspiration risk with NIVATS? The traditional monitor or methods such as BIS system, SpO2, and follow-up aspiration signs could not offer sufficient evidence to resolve the three main concerns. Recently, there have been many new methods to monitor these concerns. The density spectral array (DSA) BIS system could analyze the change of the anesthetic component. The ORI is a dimensionless index that reflects oxygenation in the moderate hyperoxic range (PaO2 100-200 mmHg).
Since it is difficult to achieve anesthesia in lower jaw and the success rate of IANB is low and there are a lot of anatomic variations for the location of inferior alveolar nerve in different races, investigators decided to compare the success rate of inferior alveolar nerve block, with and without using a panoramic radiograph in Bandar Abbas population, and see if using a panoramic radiograph can increase the preciseness of the injection.
Arthroscopic rotator cuff surgery of the shoulder is performed under general anesthesia. Pain control for after the surgery can be achieved purely with intravenous and oral pain medication or in combination with freezing of the nerves. Nerve freezing (nerve block) placed before surgery has the potential to substantially reduce the amount of inhaled anesthetic given to the patient during surgery. This can benefit the patient by minimizing the opioid usage after surgery and also reduce cost to the system in terms of duration of hospital stay. The purpose of the study is to investigate whether the inclusion of a nerve block to the general anesthetic for rotator cuff repair surgery will also reduce the amount of inhaled anesthetic and thereby lowering the environmental footprint from the anesthetic. The investigators of the proposed study plan to quantify the amount of inhaled anesthetic used for each case and will compare how the consumption is affected by whether the nerve block is applied before or after surgery. Patients will have a nerve block catheter (interscalene catheter) placed under ultrasound-guidance prior to the induction of general anesthetic by an experienced regional anesthesiologist. The nerve block catheter will be bolused with a solution to which the anesthesiologist is blinded which will either be local anesthetic or normal saline (sham). The general anesthetic will be conducted according to a the protocol with the aim of maintaining a standard anesthetic depth monitored by patient state index (PSI). Measurements of the MAC-Value (minimum alveolar concentration) of inhaled anesthetic will be recorded every five minutes and the total amount of volatile anesthetic (in ml and ml/kg) will be noted down by a blinded observer. At the end of the case the anesthesiologist blinded to the solution will inject another solution (now a saline (sham) or local anesthetic before the patient is woken up.
This study evaluates the effect of music and its influence on anesthetic requirements during total knee replacement surgery. Half of the participants will receive noise-cancelling headphones in the operating room, and the other half of participants will receive noise-cancelling headphones with music playing.
This clinical trial aims to investigate the efficacy of 20 mg Parecoxib when it is given as an addition to 20 ml 0.75% ropivacaine in patients receiving ultrasound-guided supraclavicular brachial plexus block prior to the upper limb surgeries. It is hypothesised that the addition of parecoxib to ropivacaine will provide superior sensory and motor blockades to those who only received 0.75% ropivacaine. Eighty six (n=86) patients were randomised in one-to-one ratio to either receiving 20 mg parecoxib and 20 ml 0.75% ropivacaine (n=43) or 20 ml 0.75% ropivacaine and 1 ml 0.9% saline (n=43). The primary efficacy outcomes of interest are a) The time to onsets of sensory and motor blockades (measured in minutes); b) The time to recovery from sensory and motor blockades (measured in hours). The secondary efficacy outcomes of interest are a) The presence of complete sensory blockade at 30 minutes post intervention (recorded as a binary yes-no categorical variable); b) The presence of complete motor blockade at 30 minutes post intervention (recorded as a binary yes-no categorical variable).
Penile engorgement during intraoperative period is of rare occurrence however when do happens, leads to difficulty in performing and even cancellation of elective urogenital surgery. The mechanism behind intraoperative penile engorgement is complex and involves various factors. One common myth is that penile engorgement occurs only during spinal anaesthesia and not in general anaesthesia. In this study we intend to report the incidence and management of intraoperative penile engorgement in pediatric patients undergoing urogenital operations under spinal anesthesia with/without sedation over a period of one year. The pathophysiology and role of common contributing factors leading to intraoperative penile engorgement are also discussed.
Two approved treatments for spinal anesthesia will be compared in women undergoing cesarean section. It is usual to perform cesarean sections using spinal anesthesia with a local anesthetic (bupivacaine) plus some opioid, such as sufentanil or morphine. Both have been shown to decrease postoperative pain, but we try to check if one brings more benefit than the other.
