Active clinical trials for "Agnosia"

There are very few randomized controlled trials in open splenectomy surgery, which compare paravertebral block with ESP block. The purpose of this randomized controlled trial is to compare the efficacy of ultrasound-guided paravertebral block with ESP block for perioperative analgesia in open splenectomy .

Laryngeal cancer is one of the most common tumors in otolaryngology. In China, it accounts for 1-5% of all malignancies and has an incidence of 1.13 per 100,000. Surgical resection is the most important treatment for patients who are not candidates for chemoradiotherapy or refuse chemoradiotherapy. The types of surgery include total and partial laryngectomy. Patients with laryngeal cancer often face multiple physical and psychiatric changes after surgery, such as daily large sputum production accompanied by cough, cleaning care of the air incision, fatigue, and sleep disturbances. Some patients do not actively exclude secretions due to pain, and the formation of sputum plugs causes lung inflammation, which is not conducive to postoperative recovery. Good postoperative pain management is beneficial to shorten the length of hospital stay and reduce mortality. Sufentanil is most commonly used for postoperative analgesia and has good analgesic effect, but there are some adverse effects, such as dizziness, nausea and vomiting, urinary retention, skin itching, respiratory depression, etc. As a new type of analgesic, dezocine has been widely used in clinical practice with few adverse reactions to the respiratory and circulatory system, and its application to postoperative analgesia can significantly improve the immune activity. At present, there are not many studies on continuous analgesia of dezocine, mostly single-dose analgesia studies, this study for different doses of dezocine for the postoperative analgesic effect of laryngeal cancer patients, compared with the current classic opioid analgesics, to provide a new scheme for clinical medication.

The patients who will participate in the study will be determined and informed according to the inclusion and exclusion criteria, and the patients who signed the informed consent form will be included in the study.52 patients who will undergo elective thoracotomy surgery will be divided into double-blinded 2 sided as preemptive and postoperative erector spina plane block. Intraoperative pain status of the patients will be determined by the "Nociception Level Index" device and analgesia will be provided with fentanyl. The primary aim of the study is to compare the intraoperative opioid consumption of two groups with plan block at different times. In the postoperative period, patient-controlled analgesia device will be given to both groups for rescue analgesia. The opioid consumption of the patients will be controlled in this way in the postoperative period and their pain status will be determined. The secondary aim of the study is to examine the effect of plan block application time on the postoperative period.

Postpartum analgesia is a common concern after Cesarean Section (CS). The quality of postoperative recovery is improved by opioid sparing pain control approaches. The transversus abdominis plane block (TAPB) is an effective technique for postpartum analgesia after cesarean section. Pregnancy results in thinning of the internal oblique aponeurosis; with increased incidence of missing the second pop to reach the transversus abdominis plane (TAP). The classic blind approach to the TAP is associated with several complications; so, it has been largely replaced by the ultrasound-guided approach to the TAP. The ultrasound-guided approach to the TAPB was first described by Hebbart and his colleagues in 2007.Ultrasound-guided TAPB improves the success of the block, reduces the volume of local anesthetic used and prevents the potential injury of adjacent structures. Surgical approach to the TAPB was also described, it is a quick and easy approach of establishing a reliable block. The surgeon performs an intra-abdominal approach to the TAPB; by which asepsis is easily attained, visible and tactile confirmation of correct needle placement may be achieved with no risk of damage to the viscera but care must be given to avoid injury of the inferior epigastric vessels.

Paracetamol,a classical analgesic agent,constitutes an essential component of multi-modal analgesia. This medication is generally safe, well tolerated and effective within recommended daily dose.The purpose of the study is to evaluate the efficacy and safety of Paracetamol Injection as adjuvant to morphine-based post-operative analgesia, as well as to explore the reasonable dosage of paracetamol among Chinese population under above-mentioned circumstance.

We investigated the efficacy and the safety of the pharmacokinetic model-based patient-controlled analgesia (PCA) regimens of fentanyl for postoperative analgesia after total intravenous anesthesia (TIVA).

To test if multimodal analgesia with different analgesic medication offer better pain relief, lesser side effects and is safe compared to conventionel opiod analgesia after cardiac surgery.

Main Hypothesis: laparoscopic surgery is very painful to patient during and after surgery. We would like to compare different analgesic methods.

The purpose of this study was to investigate hypothesis that preoperative administration of epidural clonidine will reduce postoperative pain and systemic inflammatory stress response better than epidural levobupivacaine.

To evaluate the effect of dexmedetomidine as an adjuvant of ropivacaine in the TAP block on cesarean section parturients under multimodal analgesia, optimize the multimodal analgesia program for cesarean section, and guide perioperative analgesia managemen。This is a single center, double-blind, randomized clinical trial.
