NCT04022057
Reconstructive foot and ankle surgery is performed under general anesthesia. Included in this spectrum of surgery are ankle arthroplasties, various fusions, corrective arthrodesis, and more. 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 with being more awake and crisp more quickly after surgery. It can also reduce cost to the system. A further benefit which has received very little attention so far, is that reducing the amount of inhaled anesthetic given also lowers the environmental footprint created by the anesthetic. For the region of the foot and ankle to be fully frozen, both the sciatic nerve and the saphenous nerve must be successfully blocked. Sciatic nerve blockade is most commonly achieved by blocking the nerve in the popliteal fossa. This block is named popliteal nerve block. The investigators will examine and quantify the amount of inhaled anesthetic used for each case and will compare how the consumption is affected by whether the nerve blocks are applied before or after surgery. Patients will have two nerve block catheters (popliteal and saphenous catheter) placed under ultrasound-guidance prior to the case by an experienced and specifically trained anesthesiologist. The catheters will be loaded with a solution to which the anesthesiologist is blinded. It will either be local anesthetic or 5% dextrose (sham). The general anesthetic will be conducted according to a research protocol with anesthetic depth being the targeted endpoint. Measurements of the required MAC-Value (minimum alveolar concentration) of inhaled anesthetic will be recorded every five minutes by a study team member. At the end of the case the anesthesiologist will be unblinded to the solution. Should the patient have received sham initially, they will now receive the full dose of local anesthetic prior to being woken up.
NCT04020601
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 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.
NCT02717728
There is currently no standard of care or best practice for managing post-operative pain for patients undergoing hip arthroscopy. Perioperative pain with these procedures can be substantial. It has been shown that up to 90% of patients in the Post-anesthesia care unit (PACU) following hip arthroscopy report pain scores of 7/10. Poor pain management following hip fracture surgery directly results in increased time spent in high cost health care areas and delayed time to ambulation. Continuous regional anesthesia following hip arthroplasty has been shown to reduce narcotic consumption and related side-effects (reduction of post-operative pain, delirium, and length of stay). The purpose of this research is to evaluate the effectiveness of a fascia iliaca nerve block in reducing post-operative pain within the first 24 hours following hip arthroscopy. Additionally, the pharmacokinetics of the drug ropivacaine will be studied via laboratory analysis of blood samples. Ultimately, the objective of this research is to develop a standard of care or best practice for the management of post-operative pain following hip arthroscopy. This study will include the entire age range of patients who are seen for hip arthroscopy at Boston Children's Hospital, for which there is a 35 year age limit. Both sexes will be included in the study. The study design will be real catheter versus a sham catheter(control). All subjects will receive general anesthesia. The catheters (real or sham) will be administered after the induction of general anesthesia and before the beginning of the surgery until 24 hours after recorded PACU admittance time. The anesthesia team placing the block will not be blinded. The orthopaedic surgeon (Dr. Yen) and all evaluators will be blinded to the absence or presence of a real catheter. In the case of a sham catheter, the anesthesia team will rig a pump to look like it is dispensing local anesthesia. To determine the pharmacokinetics of ropivicaine during standard fascia iliaca block, following induction of general anesthesia, a large bore IV catheter will be inserted for the purpose of blood draws (all patients).

NCT04352049
Preoxygenation techniques is currently considered a standard of care, but how they influence cerebral oxygenation remains largely unknown. In this study, the investigators compare three minutes tidal volume breathing versus eight vital capacity, deep breaths (8DB) technique. Forty-eight patients scheduled for surgery under general anesthesia were included in a randomized study design. The main endpoints were arterial partial pressure of O2 (PaO2) and regional cerebral oxygen saturation (rScO2 ; INVOS TM -5100- C) which were measured at baseline (T1), end of pre-oxygenation (T2) and after desaturation during apnoea to 95% (T3).

The aim of this prospective randomized study is to investigate comparatively the effect of neostigmine-atropine versus sugammadex on speed and quality of recovery and on postoperative cognitive function \& behavior in children undergoing ENT surgery under general anaesthesia.
NCT03480165
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).
NCT03438253
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.
