Background: Peripheral nerve injury is a complication that can occur after general anesthesia. It significantly impairs the patient’s quality of life and may lead to permanent disability. Nerves in several areas can be damaged during the perioperative period, but it is very rare that numbness of the lower lip is caused after general anesthesia. Case: A 73-year-old man with diabetes mellitus underwent urological surgery under general anesthesia. The day after surgery, he complained of numbness on the right lower lip caused by a mental nerve injury. Diabetic mononeuropathy or neurapraxia related to mechanical compression was considered a possible cause. The symptoms resolved spontaneously after six weeks.Conclusions: Mental nerve injury is a rare perioperative complication in surgical patients under general anesthesia. In this case, patients should be reassured and advised to avoid injuries to the mouth and lips. However, specific treatment is not required.

Different Doses

Objective. To explore the effect of different doses of propofol and nerve block combined with general anesthesia on the intraoperative anesthesia and postoperative awakening and cognitive function in elder patients with knee osteoarthritis (OA). Methods. According to the inclusion criteria for research object, we selected 98 elderly patients with knee OA who needed surgery and were admitted to our hospital from January 2019 to January 2021 for the study. Patients were divided into the low dose group (given 2 mg/kg propofol by pumping under constant speed during surgery) and the high dose group (given 4 mg/kg propofol by pumping during surgery) by the number table method to compare their indicators including the intraoperative anesthesia effect, with 49 cases in each group. Results. No between-group difference was shown in the anesthesia time and postoperative VAS scores, but the awakening time of the low dose group was significantly shorter than that of the high dose group (P<0.05); the differences in heart rate (HR) values at various time points between the two groups were not obvious, but the high dose group obtained significantly higher HR values at T4 than the low dose group; the mean arterial pressure (MAP) values of both groups were significantly reduced at Ti and then returned to the level before anesthesia (P>0.05); the bispectral index scores (BIS) of both groups experienced a marked drop at Ti and then recovered gradually, but failed to return to the level at T0 till the end, and a between-group difference in BIS indexes presented at Ti; the plasma corticosterone (CORT) concentration at Ti of both groups were significantly lowered and then returned to the level at T0, with no between-group difference; and compared with the low dose group, the high dose group achieved slightly lower mini-mental state examination (MMSE) scores at 24-72 h after surgery, with no significant difference between them (P>0.05). Conclusion. The therapy of different doses of propofol and nerve block combined with general anesthesia has no significant effect on the cognitive function in elderly knee OA patients after surgery. With the nerve block improving the analgesic effect, a low dose of propofol is good for the postoperative awakening of patients. Different doses of propofol inhibited the stress response to a different degree and produced good anesthesia outcomes in elderly patients, but comparatively speaking, a low-dose propofol ensures more smooth indexes and less effect on the intraoperative hemodynamics.

Background: Marginal Mandibular nerve, a branch of facial nerve, emerges at the lower part of the anterior border of parotid gland. It supplies risorius, muscles of lower lip and chin and joins mental nerve. This nerve has an important relationship with the lower border of mandible and is likely to be damaged during procedures in or around the submandibular area and can lead to certain morbid conditions like deviation of angle of mouth, drooling of saliva and difficulty in phonation.Methods: Sixty formalin preserved specimens of head and neck were used for studying the branching pattern of marginal mandibular nerve. The present study was conducted in the department of Anatomy Govt Medical College Srinagar over a period of two and a half years from 2015 to 2017. Cadaveric dissection was also used in the study during the routine teaching of undergraduate MBBS and BDS students in the department. The photographs of the variations seen during the study were taken.Results: In Forty-seven specimens (78.33%) there was a single branch of marginal mandibular nerve, in 10 specimens (16.6%) there were two branches of marginal mandibular nerve and in three specimens (5.0%) the marginal mandibular nerve was having three branches.Conclusions: From the above study it was concluded that marginal mandibular nerve can have two or three branches. Therefore, it is advisable to take due care during surgical procedures in the lower part of face and upper part of neck to preserve marginal mandibular nerve and to ensure cosmesis and prevent morbidity.

Abstract Background Breast cancer has continued to be the most common cancer afflicting women, accounting for 31% of all new cancer cases in the female population. Every year, thousands of patients undergo surgery in the region of the breast and axilla. Surgery is one of the mainstays of treatment, and a procedure called modified radical mastectomy (MRM) is now a standard surgical treatment for early-stage breast cancers. Objective To evaluate the Efficacy of combined ultrasound guided Pectoral Nerve Block (PECS I block and PECS II block) using Bupivacaine with or without Magnesium Sulfate in modified radical mastectomy under general anathesia. Patients and Methods After obtaining approval from the medical ethical committee in Ain Shams University This study was conducted in the operating theatres of Ain Shams University Hospitals. It included Thirty Female patients undergoing Modified Radical Mastectomy were divided randomly into two groups, each group consisted of 25 patients group I in which patients received general anesthesia followed by PECS BLOCK using only bupivacaine 0.25 % and group II in which patients received general anesthesia followed by PECS BLOCK using bupivacaine 0.25 % plus magnesium sulfate 50% (200mg). Results The two groups were adequately monitored and assessed post-operatively and they were compared regarding analgesic outcome by using the visual analogue scaling system, besides, recording time for first for analgesic need and total consumption of opioid and analgesic in the 1st 24 postoperative hours. Demographic data and post operative hemodynamics were also assessed. Conclusion The addition of 200 mg of magnesium sulfate to bupivacaine in an ultrasound-guided Pectoral Nerve Block significantly reduce postoperative opioid consumption, prolong the duration of the analgesia, and reduce the VAS score without significant side effects after Modified Radical Mastectomy under general anesthesia.
