Filter by:To investigate whether midazolam has any effect on postoperative pain in outpatient surgery, the investigators will assess the impact of different midazolam doses on pain scores 24h, 7 days and 3 months after ambulatory surgery. The investigators hypothesize that patients being administered higher midazolam doses will refer more pain.
Study Background Osteoarthritis of the knee is a common degenerative musculoskeletal condition which affects nearly five million people in the United Kingdom. Some patients will require total knee replacement surgery if their symptoms of pain and disability are not controlled adequately by so-called 'conservative' measures such as weight-loss, activity modification and analgesic (pain-killer) medication. Over the past ten years our understanding of pain-relief strategies during total knee replacement, often termed 'Enhanced Recovery' principles, has helped improve patient care and reduced length of hospital admission. 'Enhanced Recovery' principles recommend the use of analgesic medications which can be delivered in a variety of ways e.g. tablets and injections. This is termed 'multi-modal' analgesia. Prior to total knee replacement, the patient will receive an injection around the nerves in the spine (regional anaesthesia) which numbs the patient from the waist down and allows the surgeon to perform the operation in a safe and pain-free manner. During the operation, surgeons often choose to deliver extra local anaesthetic to prolong the degree of pain-relief in the immediate post-operative period. This can enable patients to mobilise early and is associated with greater long-term satisfaction. There are two main methods of delivering this extra form of pain-relief during the operation. Peri-articular injection involves multiple injections of local anaesthetic into the soft-tissues surround the knee. In contrast, Intra-articular injection involves a single injection directly into the knee joint once the operation is finished. Currently, there is no clear evidence available to Orthopaedic surgeons to inform us which technique is better at providing pain relief for patients undergoing total knee replacement surgery. All patients undergoing total knee replacement surgery for osteoarthritis of the knee will be invited to participate in this study. We intend to recruit a total of 120 patients. During the patient's total knee replacement surgery, they shall receive an injection of local anaesthetic around the soft-tissues of the knee (Peri-Articular Injection) or directly into the knee joint itself (Intra-Articular Injection). The decision regarding which treatment they receive is decided entirely by randomisation. Following the operation, a member of the research team will assess the patient on the ward to collect information regarding levels of pain and overall satisfaction. The type of injection received shall be kept secret from both the patient and the member of the research team collecting the post-operative pain scores. After the patient has been safely discharged from hospital, we intend to follow-up all participants for one year. This will involve routine clinic appointments at six weeks and twelve months following surgery. This will involve review and clinical examination by a member of the orthopaedic team who have treated the patient whilst in hospital and/or a member of the research team. In addition, all patients will be asked to complete a questionnaire at twelve months regarding their level of function and pain. These questionnaires have been used widely in the medical literature and have a strong evidence base for their use. What is the aim of this study? The aim of this study is compare the amount of pain relief provided by two different methods of local anaesthetic injection techniques used in total knee replacement surgery. In addition, we would like to know if this influences the patient's immediate and long-term recovery after surgery.
This is a prospective, randomized control trial to compare SPANK block combined with adductor canal block to adductor canal block alone in treatment of post-operative pain after total knee arthroplasty. The primary outcome is pain control, which will be measured throughout the post-operative course using morphine equivalents of opioid analgesics used during the first 24 hours after surgery. Secondary outcomes include pain scores recorded at 4, 8, 12, 16, 20, and 24 hours post-operatively, cumulative pain score, incidence of post-operative nausea and vomiting, and extent of motor blockade. The study will aid in answering the question of whether SPANK block is an effective adjunct in preventing pain and decreasing opioid requirement after TKA.
Recent evidence has shown that the onset and intensity of post-operative pain are significantly related to the amount of residual pneumoperitoneum at the end of the surgical procedure. In addition, the use of low pressures of carbon dioxide (CO2) for induction of the pnemoperitoneum has been associated with a reduction in post-operative pain, probably due to a lower abdominal distension and a consequent reduced compression of the pelvic, abdominal and sub-diaphragmatic pain nerve fibers. The reduction of the residual pnemoperitoneum at the end of the surgical procedure could therefore play a key role in the reduction of post-operative pain, with consequent greater comfort for the patient and reduction of the use of analgesics. In view of the available evidence, the aim of the present study is to evaluate whether the application of Jackson-Pratt drain, for one hour from the end of the surgical procedure, can significantly reduce post-operative pain and the need of analgesics in patients undergoing laparoscopic gynecological surgery.
Chronic postoperative pain (CPP) remains a disturbing and obscure clinical problem, which could last for more than 3 months after surgery. The aim of present study was to assess the prevalence of CPP, investigate its impact on life quality and explore its potential risk factors. After informed consent was signed, patients receiving surgery under general anesthesia in Peking Union Medical College Hospital and other medical centers participating in this study during 2018 will be included. Patients' preoperative information will be collected from medical record, including basic demographic data, primary disease and previous chronic diseases. Intraoperative information will be obtained from anesthesia record, including surgical scope, duration, length and location of incisions and blood loss. Acute pain will be evaluated in the ward of the department of surgery, when an app will be installed on patients' mobile phones. Our long-term postoperative follow-up would be performed by sending out survey questionnaires via this app in the 4th, 8th, 16th, 32th, and 48th weeks after surgery. The survey covers questions regarding the intensity, characteristic, location and impact on daily activities of CPP. Information regarding treatment of CPP will also be collected, if any. All the data gained will be summarized in our database and analyzed.
The aim of the current pilot study is to investigate whether perioperative dysregulated systemic lipid mediator pathways (more specifically increased pro-inflammatory and decreased anti-inflammatory pathways) are associated with slower resolution of pain after surgery and increased risk for development of persistent postsurgical pain (PPSP). In addition, we will look for correlations between the pro-resolving lipid mediator profile and Quality of Recovery (QoR-15), duration of hospital stay, and frequency of complications, e.g. wound infections.
compare the analgesic efficacy of the combination of bupivacaine and morphine, bupivacaine and fentanyl and bupivacaine and ketamine in alleviating post operative pain following laparoscopic cholecystectomy.

assess the effect of using reciprocating motion with reciproc files versus adaptive motion using twisted file adaptive on postoperative pain after instrumentation of necrotic mandibular molars.
Intravenous magnesium has been studied in pediatrics to reduce agitation after sevoflurane anesthesia in children undergoing adenotonsillectomy, reduce intraoperative rocuronium requirements, prevent laryngospasm and coughing after removal of the endotracheal tube in patients undergoing adenotonsillectomy. The aim of this study is to investigate the role of intravenous magnesium sulfate on postoperative pain management in paediatrics and to compare it with its effect when administered caudally in children undergoing lower abdominal surgeries.
