简要总结
Arthroscopic knee surgery is a minimally invasive operation. Postoperative pain usually occurs, especially within 24 hours after surgery, the incidence of pain can be more than 76%. Pain will affect the patient's emotions and life, cause adverse effects, and even lead to postoperative delirium. This study aimed to investigate the clinical effect of ultrasound-guided high fascia iliaca compartment block(H-FICB) in patients undergoing knee arthroscopy and to compare it with the normal method which is femoral nerve block combined with a sciatic nerve block to choose the better way. A double-blind, randomized controlled trial was conducted with 44 patients, aged 18-65 years, ASA I-III, who were scheduled to undergo arthroscopic knee surgery in our hospital were selected, the patients were divided into Group A and Group B by random number table method, with 22 patients in each group. Group A was subjected to the H-FICB under ultrasound guidance before general anesthesia, given 0.375% ropivacaine 30 ml. Group B received ultrasound-guided femoral nerve block combined with sciatic nerve block before general anesthesia, given 0.375% ropivacaine 30 ml.
The mini-mental State Examination was used to assess all the patients' primary cognitive status one day before surgery. The initial acting time and the degrees of sensory block and motor block were recorded after the nerve block was completed. Perioperative variables were recorded to be compared. The investigators used the visual analog scale to assess patients' pain degree with postoperative, recorded the occurrence of adverse events such as postoperative nausea and vomiting(PONV), delayed emergence from anesthesia, and respiratory depression. The confusion assessment method was used to assess whether patients experienced delirium.
详细描述
- Study design and setting 44 patients undergoing arthroscopic knee surgery under general anesthesia, gender, aged 18-65 years, American Society of Anesthesiologists (ASA) physical status I-III. Exclusion criteria: MMSE of 1 day before surgery < 27, communication and dysfunction (e.g., vision, hearing), cerebrovascular history, local anesthetic allergy, opioid allergy, puncture site infection, abnormal clotting.
- Subjects Patients were allocated randomly to A group (the high fascia iliaca compartment block group) and B group (the femoral nerve block combined with sciatic nerve block group) according to a computer-generated random number table. All patients and an investigator who was responsible for follow-up during 48 postoperative hours were blinded to the randomization groups. In addition, during preoperative visits, the investigators instructed patients on how to use the patient-controlled intravenous analgesia (PCA) device for pain management, as well as how to use the visual analog scale to evaluate pain at rest and while coughing. All the bispectral index (BIS) value in the present study was maintained between 40 and 60 during surgery. All patients voluntarily signed informed consent.
- General anesthesia Patients were monitored by electrocardiogram, pulse oximetry, and non-invasive blood pressure (one measurement every 3 min) while entering the operation room. A radial artery catheter was also placed for invasive arterial pressure and blood gas monitoring. The induction of general anesthesia was performed intravenously with sufentanil 0.5 µg/kg, propofol 1-2 mg/kg, and rocuronium 0.6 mg/kg. Endotracheal intubation was performed with a double-lumen tube. Sevoflurane was used at a minimal alveolar concentration (MAC) of 0.8-1, remifentanil and propofol were used for the maintenance. Fluid management was at the discretion of the attending anaesthesiologist.

结局指标
主要结局
Change from Baseline visual analogue scale
时间窗: 30 minutes after extubation and 6 hours and 12 hours
Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0 to 100. A higher score indicates greater pain intensity. Based on the distribution of pain Visual Analogue Scale scores in post-surgical patients (knee replacement, hysterectomy, or laparoscopic myomectomy) who described their postoperative pain intensity as none, mild, moderate, or severe, the following cut points on the pain Visual Analogue Scale have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).
The mini-mental State Examination
时间窗: one day before the operation.
The mini-mental State Examination is effective as a screening tool for cognitive impairment in older, community-dwelling, hospitalized, and institutionalized adults. Assessment of an older adult's cognitive function is best achieved when it is done routinely, systematically, and thoroughly. The Mini-Mental State Examination (MMSE) or Folstein test is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. Any score of 24 or more (out of 30) indicates normal cognition. Below this, scores can indicate severe (≤9 points), moderate (10-18 points), or mild (19-23 points) cognitive impairment. The raw score may also need to be corrected for educational attainment and age.
