Introduction: It is a well recognized fact that a significant proportion of patients operated on for lumbar disc herniation exhibit a poor outcome, regardless of the apparent technical success of the operative procedure itself. Aim: to identify a set of widely available variables that accurately predict short-term outcome after discectomy and to develop a predictive model based upon those variables. Patients and methods: Basic demographic, clinical and radiological variables were evaluated in a group of 70 patient operated on for disc herniation. Outcome was assessed using VAS and RM scales 6 months postoperatively and correlated to aforementioned variables. Results: Preoperative pain intensity and duration, age and type of disc herniation were all shown to be statistically significant predictors of short-term outcome, unlike sex, type of radiological investigation and preoperative tension sign testing results. Multivariate regression analysis including only variables previously identified as good outcome predictors revealed that the pain intensity exhibited the strongest correlation with outcome, followed by pain duration, type of disc herniation and age. Even though MR scan was more sensitive in detecting disc extrusion than CT (sensitivity of 100% versus 65%, respectively), the presence of preoperative MR scan did not influence the outcome. Conclusion: The study identified a set of widely available and easily attainable variables as fair predictors of short-term outcome after lumbar discectomy. Subsequent logistic regression resulted in a predictive model whose accuracy is to be determined in another prospective study
Background: Martin-Gruber anastomosis (MGA) is the well known anostomosis that occur at the various levels between the median and ulnar nerves. This anastomosis involves axons leaving either the main trunk of median nerve or the anterior interosseous nerve, crossing through the forearm to join the ulnar nerve. Knowledge of the incidence of this anastomosis is necessary because MGA can cause confusion in the assesment of nerve injuries and compressive neuropathies.
a ssessment of depth of anesthesia is the basis in anesthesiologist ' s work because the occurrence of awareness during general anesthesia is important due to stress, which is caused in the patient at that moment, and due to complications that may arise later. There are subjective and objective methods used to estimate the depth of anesthesia. The aim of this study was to assess the depth of anesthesia based on clinical parameters and on the basis bispectral index, and determine the part of bispectral monitoring in support to clinical assessment. Material and methods: Sixty patients divided into two groups were analyzed in a prospective study. In first group (group 1), the depth of anesthesia was assessed by PRST score, and in the second group (group 2) was assessed by bispectral monitoring with determination PRST score concurrently. In both groups PRST score was assessed in four periods, while bispectral monitoring is used continuously. For analysis were used the BIS index values from the equivalent periods as PRST scores. PRST score value 0-3, and BIS index 40-60 were considered as adequate depth of anesthesia. The results showed that in our study were not waking patients during the surgery. In the group where the depth of anesthesia assessed clinically, we had a few of respondents (13%) for whom at some point were present indicators of light anesthesia. Postoperative interview excluded the possibility of intraoperative awareness. In the second group of patients and objective and clinical assessment indicated at all times to adequate depth of anesthesia. Conclusion: The use of BIS monitoring with clinical assessment allows anesthesiologists precise decision-making in balancing and dosage of anesthetics and other drugs, as well as treatment in certain situations.
The aim:of this study was to compare two methods of polypropylene mesh fixation for inguinal hernia repair according to Lichtenstein using fibrin glue and suture fixation.Material and Methods:The study included 60 patients with unilateral inguinal hernia, divided into two groups of 30 patients – Suture fixation and fibrin glue fixation.All patients were analyzed according to:age, gender, body mass index (BMI), indication for surgery–the type, localization and size of the hernia, preoperative level of pain and the type of surgery. Overall postoperative complications and the patient’s ability to return to regular activities were followed for 3 months.Results and discussion:Statistically significant difference in the duration of surgery, pain intensity and complications (p<0.05) were verified between method A, the group of patients whose inguinal hernia was repaired using polypropylene mesh–fibrin glue and method B, where inguinal hernia was repaired with polypropylene mesh using suture fixation. Given the clinical research, this systematic review of existing results on the comparative effectiveness, will help in making important medical decisions about options for surgical treatment of inguinal hernia.Conclusions:The results of this study may impact decision making process for recommendations of methods of treatment by professional associations, making appropriate decisions on hospital procurement of materials, as well as coverage of health funds and insurance.
