OBJECTIVE:
To summarize the research progress of anterior cutaneous nerve injury and repair in knee arthroplasty.
METHODS:
The relevant literature at home and abroad in recent years was reviewed and summarized from the anatomy of anterior cutaneous nerve, nerve injury grade, clinical manifestations, prevention and treatment of anterior cutaneous nerve.
RESULTS:
The anterior cutaneous nerve injury is a common complication of knee arthroplasty. Because the anterior cutaneous nerve branches are many and thin, and mainly run between the first and second layers of fascia, this level is often ignored during surgical exposure. In addition, the knee arthroplasty does not routinely perform the exploration and repair of the cutaneous nerve. So the anterior cutaneous nerve injury is difficult to avoid, and can lead to postoperative skin numbness and knee pain. At present, studies have explored the feasibility of preventing its occurrence from the aspects of improved incision and intraoperative separation of protective nerve. There is no effective prevention and treatment measures for this complication. For patients with skin numbness after knee arthroplasty, the effectiveness of drug treatment is not clear. Local nerve block or nerve excision can be used to treat patients with painful symptoms after knee arthroplasty considering cutaneous pseudoneuroma.
CONCLUSION
Knee arthroplasty is widely used and anterior cutaneous nerve injury is common in clinic. In the future, more high-quality clinical studies are needed to further explore the prevention and treatment measures of this complication and evaluate the clinical benefits obtained.

Previous studies have shown that postoperative cognitive dysfunction (POCD) is related to multiple factors including age, postoperative trauma, inflammation, postoperative pain, and anesthesia, among which postoperative pain is thought to play an important role in the development of POCD. This review summarizes the recent findings in the study of the role of postoperative pain in the pathogenesis of POCD in light of nerve injuries, neural remodeling and stress, and the progress in the prevention and treatment of POCD in elderly patients. It is of vital important to assess the postoperative pain and formulate adequate analgesic regimens for effective prevention and management of POCD to protect the brain functions of elderly patients.

Total knee arthroplasty has become one of the effective operation methods on end-stage knee osteoarthritis. However,the postoperative pain has been plaguing the clinicians. The cause of postoperative pain can be divided into iatrogenic, prosthesis and patient. Pain treatment in perioperative period includes preoperative education, analgesia in advance, and the selection and design of reinforcement; during operation mainly includes the appropriate surgical approach, keep the balance of soft tissue around the knee joint, cocktail analgesia pain around the knee joint; after operation mainly includes oral analgesic drugs, femoral nerve tissue and patient controlled analgesia. And the multimodal analgesi.a which is the analgesic methods combined application in perioperative period raised in resent years fully intervene the pain in perioperative period,so that it can effectively reduce the pain of patients after knee replacement, promote the patients do functional exercise more better and get better operation result.

The levels of pain, duration of approaching and closure, and surgical exposure associated with intercostal thoracotomy were compared between muscle-sparing and traditional techniques in 20 dogs. Postoperative pain was assessed based on numerical pain scores using behavioral observation, heart rate, respiratory rate, and wound palpation. Time for approaching and closure were measured, and the extent of intrathoracic organ exposure for the surgical procedures was described for each technique. There were significant differences in numerical pain scores at 2 h as well as 1, 2, 3, 4, 5, 6, and 7 days after surgery between the two groups (p < 0.0001). There was no significant (p = 0.725) difference in times for approaching and closure between the two groups. Compared to the traditional method, the muscle-sparing technique also achieved the desired exposure without compromising exposure of the target organs. Our results suggest that the muscle-sparing technique is more effective than the traditional method for providing a less painful recovery during the first 7 days after intercostal thoracotomy. Additionally, the muscle-sparing technique is as effective as the traditional modality for providing an appropriate time for approaching and closure during intercostal thoracotomy as well as adequate organ exposure for the surgical procedures.

BACKGROUND/AIMS: Postoperative early feeding has many advantages, and current guidelines recommend the early diet or enteral feeding after gastrointestinal surgery. However, there are controversies in emergency situation. The aim of this study was to assess the safety of early enteral feeding in patients underwent emergency gastrointestinal (GI) surgery. METHODS: We reviewed the patients underwent emergency GI surgery by single surgeon from March 2008 to December 2010, retrospectively. The early feeding was defined when feeding was started within 72 hours after operation. RESULTS: Fifty-three patients were enrolled. Men were 31, with mean 60.6 (+/-18.5) years old age. Thirty-three patients were treated in the intensive-care unit after operation. The most common cause of operation was bowel perforation, and followed by intestinal obstruction. Segmental resection with primary anastomosis of small bowel is the most common operation. Thirty-two of them started the diet within 48 hours postoperatively. Twenty-nine patients had post-operative complications. Wound complications were the most common, and followed by the abdominal pain, and ileus. Wound complications were developed in 18 patients, and the post-feeding abdominal pain was in 7 patients. Anastomotic leakage and intraabdominal abscess were developed in 2 patients, and 1 patient required reoperation to treat the anastomotic disruption. One patient developed pneumonia and sepsis, and resolved under conservative treatment. There was no mortality in these patients. CONCLUSIONS: Early enteral feeding may be safe in cases of emergency GI surgery. However, it may require further studies to confirm the safety and feasibility of the early feeding in emergency situations.

Pectus excavatum is the common congenital chest wall deformity in children, and Nuss procedure is the conventional surgical treatment for this disease. Nuss procedure is superior to Ravitch correction for it is less harmful in terms of the surgical technique. However, Nuss procedure is associated with severe postoperative pain, thus adequate postoperative analgesia is important. In this review, factors that influence the postoperative pain after Nuss procedure, the pain managements, the related complications and the side effects of drugs are discussed.

OBJECTIVES:
Primary trigeminal neuralgia (PTN) is a common cranial nerve disease in neurosurgery, which seriously endangers the physical and mental health of patients. Percutaneous balloon compression (PBC) has become an effective procedure for the treatment of PTN by blocking pain conduction through minimally invasive puncture. However, the recurrence of facial pain after PBC is still a major problem for PTN patients. Intraoperative balloon shape, pressure and compression time can affect the prognosis of patients with PBC after surgery. The foramen ovale size has an effect on the balloon pressure in Meckel's lumen. This study aims to analyse the predictive value of foramen ovale size for postoperative pain recurrence of PBC by exploring the relationship between foramen ovale size and postoperative pain recurrence of PBC.
METHODS:
A retrospectively analysis was conducted on the clinical data of 60 patients with PTN who were treated with PBC in Department of Neurosurgery, Affiliated Hospital of Chengde Medical College from November 2018 to December 2021. We followed-up and recorded the Barrow Neurological Institute (BNI) pain score at 1, 3, 6 and 12 months after operation. According to the BNI pain score at 12 months after surgery, the patients were divided into a cure group (BNI pain score I to Ⅱ) and a recurrence group (BNI pain score Ⅲ to Ⅴ). The long diameter, transverse diameter and area of foramen ovale on the affected side and the healthy side of the 2 groups were measured. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used for analysis the relationship between the recurrence of pain and the long diameter, transverse diameter, area of foramen ovale on the affected side, and aspect ratio, transverse diameter ratio, area ratio of foramen ovale on the affected side to healthy side in the 2 groups.
RESULTS:
At the end of 12 months of follow-up, 50 (83.3%) patients had pain relief (the cured group), 10 (16.7%) patients had different degrees of pain recurrence (the recurrence group), and the total effective rate was 83.3%. There were no significant differences in preoperative baseline data between the 2 groups (all P>0.05). The long diameter of foramen ovale on the affected side, the long diameter ratio and area ratio of foramen ovale on the affected/healthy side in the cured group were significantly higher than those in the recurrence group (all P<0.05), and there were no significant differences in the transverse diameter and area of foramen ovale on the affected side and the transverse diameter ratio of foramen ovale on the affected/healthy side between the 2 groups (all P>0.05). The ROC curve analysis showed that the AUC of the long diameter of foramen ovale on the affected side was 0.290 (95% CI 0.131 to 0.449, P=0.073), and the AUC of aspect ratio of foramen ovale on the affected side to healthy side was 0.792 (95% CI 0.628 to 0.956, P=0.004). The AUC of area ratio of foramen ovale on the affected side to healthy side was 0.766 (95% CI 0.591 to 0.941, P=0.008), indicating that aspect ratio and area ratio of foramen ovale on the affected side to healthy side had a good predictive effect on postoperative pain recurrence of PBC. When aspect ratio of foramen ovale on the affected side to healthy side was less than 0.886 3 or area ratio of foramen ovale on the affected side to healthy side was less than 0.869 4, postoperative pain recurrence was common.
CONCLUSIONS
Accurate evaluation of the foramen ovale size of skull base before operation is of great significance in predicting pain recurrence after PBC.
