RESUMEN
Objective:To understand the occurrence of major adverse cardiac events (MACE) during the perioperative period of cervical spine surgery and analyze its risk factors.Methods:A retrospective analysis of 426 cervical spine surgery patients admitted to the from March 2017 to March 2021. The basic information of the patients, including gender, age, body mass index (BMI), underlying diseases, and the Charlson comorbidity index (CCI) was calculated based on the underlying diseases.The preoperative serum cardiac troponin I(cTnI) level and the operation-related indicators were collected,including the type of cervical spine surgery, surgical procedure, approach, duration of surgery, duration of anesthesia, intraoperative bleeding, postoperative pain visual analogue scale (VAS), and electrolyte disturbances. Count data were expressed as cases (%), and comparisons between groups were made using the χ 2 test; logistic regression models were applied to perform a multifactorial analysis of the factors influencing the perioperative occurrence of MACE in patients undergoing cervical spine surgery. Results:Among the 426 patients, 54 (12.68%) experienced MACE during the perioperative period, including 4 cases of unstable angina (7.41%), 4 cases of acute myocardial infarction (7.41%), 33 cases of severe arrhythmia (61.11%), and 13 cases of acute heart failure (24.07%). The results of multivariate logistic regression analysis showed that the older the age group (50-59 years old: odds ratio=1.34, 95% confidence interval: 1.14-1.78; 60-69 years old: odds ratio=1.48, 95% confidence interval: 1.20-1.86; 70-79 years old: odds ratio=1.71, 95% confidence interval: 1.34-2.57; 80-89 years old: odds ratio=1.95, 95% confidence interval: 1.46-2.85), as well as females, CCI scores>3, and preoperative cTnI>0.04 μg/L, postoperative VAS score>5, and electrolyte disorders are all influencing factors for the occurrence of MACE in cervical spine surgery patients during the perioperative period (odds ratios of 1.84, 2.12, 2.34, 2.57, 2.20, 95% confidence intervals of 1.34-2.68, 1.50-3.41, 1.63-3.72, 1.53-4.01, 1.43-3.69, all P<0.05). Conclusions:The incidence of MACE in the perioperative period of cervical spine surgery is relatively high. Elderly age, female, high CCI score, high preoperative serum cTnI, postoperative pain and electrolyte disturbance are independent risk factors for the perioperative period of cervical spine surgery.
RESUMEN
Objective:To investigate the effect of external dissection and internal ligation (MMH) in the treatment of grade Ⅲ to Ⅳ mixed hemorrhoids with anorectal resting hypertension and its prognostic risk factors.Methods:The clinical data of 48 patients with grade Ⅲ-Ⅳ mixed hemorrhoids complicated with rectal and anal resting hypertension treated by MMH in Nanjing Jiangbei people′s Hospital Affiliated to Nantong University from February 2018 to February 2020 were analyzed retrospectively (observation group), including 24 males and 24 females; The age ranged from 22 to 55 (41.87±7.52) years. Another 48 patients with grade Ⅲ-Ⅳ mixed hemorrhoids complicated with anorectal resting hypertension treated by PPH were selected as the control group, including 20 males and 28 females; The average age was (42.68±7.14) years. The clinical effective rates , pain score at 6, 24 and 72 h after operation, postoperative complications were compared between the two groups. Multiple logistic regression was used to analyze the related risk factors affecting the prognosis.Results:There was no significant difference in VAS score between the two groups at 6 h after operation ( t=0.25, P=0.807); the VAS score of the observation group at 24 h and 72 h after operation was lower than that of the control group ( t=7.044, P<0.001; t=5.307, P<0.001); the total effective rate of the observation group was higher than that of the control group (93.75% vs 77.08%, χ2=5.35, P=0.021); the total incidence of postoperative anal edema, defecation difficulty, bloody stool, anal pain and fecal incontinence in the observation group was lower than that in the control group, the difference was statistically significant (12.50% vs 33.33%, χ2=5.879, P=0.015). Age, course of disease, grading of internal hemorrhoids and treatment methods were related to the prognosis of patients ( P<0.05); logistic regression analysis showed that age (> 45 years), course of disease (>10 years), grade of internal hemorrhoids (grade Ⅳ) and treatment (PPH) were independent risk factors for prognosis of patients ( P<0.05). Conclusions:MMH has less complications, less postoperative pain and satisfactory curative effect in the treatment of Ⅲ to Ⅳ mixed hemorrhoids and anorectal resting hypertension. The older the patients, the longer the course of disease, the higher the degree of internal hemorrhoids and the choice of treatment methods were the risk factors for the prognosis. Early diagnosis and reasonable treatment are helpful to improve the prognosis of patients.
