Evaluation of Changes in Serum Concentration of Sodium in a Transurethral Resection of the Prostate/ Евалуација На Промените Во Серумската Концентрација На Натриум При Трансуретралнa Ресекција На Простатa

Abstract

Introduction and objectives: The purpose of this study was to evaluate changes in serum electrolytes during Transurethral resection of the prostate (TURP) and to evaluate the degree of correlation of hyponatremia and the factors that affect the incidence of TURP syndrome and to show the impact of the duration of the procedure on the severity of hyponatremia due to absorption of irrigation fluid in the systemic circulation.

Materials and Methods: This study examined 60 male patients planned for elective TURP. The level of serum electrolytes are determined by taking venous blood samples preoperatively and Postoperatively and when the duration of the operation was longer than 60 minutes, the level of serum electrolytes was determined intraoperative. The amount of used irrigation fluid, the weight of resection prostate, and duration of surgery, were also followed. Patients were divided in two groups according to the length of the surgical procedure: Group 1 (30- 60 min) and Group 2 (> 60 min).

Results: Statistically significant reduction of serum sodium and the elevation of the potassium level in serum observed postoperatively and was directly proportional to the volume of of the used irrigation fluid, the duration of the procedure and volume of the resected prostate.

Conclusions: To evaluate changes in serum electrolyte during TURP is simple and economical method for the indirect estimation of irrigation fluid absorption into the systemic circulation during TURP and opportunity for early identification of TURP syndrome

Effect of Adding Dexamethasone as a Ropivacaine Adjuvant in Ultrasound-Guided Transversus Abdominis Plane Block for Inguinal Hernia Repair

Abstract

Background: The transverses abdominals plane block (TAP) is a regional anesthesia technique that provided analgesia to the parietal peritoneum, skin and muscles of the anterior abdominal wall. The aim of this randomized double-blind study was to evaluate postoperative analgesia on patients undergoing open inguinal hernia repair under general anesthesia (GA), (GA + TAP) block preformed with ropivacaine and (GA + TAP-D) block preformed with ropivacaine and 4 mg dexamethasone.

Methods: 90 (ASA I-II) adult patients for unilateral open inguinal hernia repair were included in this study. In group I (n = 30) patents received only general anesthesia (GA). Patients in group II (n = 30) received GA and unilateral TAP block with 25 ml of 0.5% ropivacaine and the patients in group III (n = 30) received GA and unilateral TAP-D block with 25 ml of 0.5% ropivacaine + 4 mg Dexamethadsone. In this study we assessed the pain score - VAS at rest at 2, 4, 6, 12 and 24 hours after the operation and the total analgesic consumption of morphine over 24 hours.

Results: There were statistically significant differences in the VAS scores between group I, group II and group III at all postoperative time points - 2hr, 4hr, 6hr, 12hr and 24hr. (p < 0.00001). The cumulative 24 hours morphine consumption after the operation was significantly lower in group III (5.53 1.21 mg) than in group II (6.16 2.41 mg) and group I (9.26 2.41 mg). This difference is statistically significant (p < 0.00001).

Conclusion: Concerning the inguinal hernia repair we found better postoperative pain scores and 24 hours reduction of the morphine consumption in group III (GA and TAP-D block) compared with group I (GA) and group II (GA + TAP block).

Insulin Resistance, Glycemia and Cortisol Levels in Surgical Patients who Had Preoperative Caloric Load with Amino Acids

Abstract

Introduction: Surgical stress response, results in elevated levels of anti-insulin hormones and reduced insulin secretion. This hormonal state may be detrimental for surgical patients due to the presence of insulin resistance and hyperglycemia. Additionally, pre-operative fasting favors this conditions. The aim of this study is to analyze the impact of pre-operative caloric load, with 440kJ from amino acid infusions on the levels of glucose, cortisol and insulin resistance in surgical patients.

Material and Methods: The study included 20 female patients scheduled for mastectomy, aged 30-60 years without diabetes and BMI < 30 m2, divided into two groups. The study group A, the evening before the surgery, received 1000 ml amino acid infusions, while the control group B didn′t receive any infusion. In both groups glucose, C-peptide and cortisol levels were determinate preoperatively and postoperatively. From the obtained C-peptide and glucose values, with the help of computer model (HOMA2*), the insulin resistance (IR), functionality of beta cells (BETA) and insulin sensitivity (IS) were calculated.

Results: Postoperative values of insulin resistance (0.94 ± 0.12 vs 1.13 ± 0.2; p = 0.02) and glucose (4.79 ± 0.5 vs 5.77 ± 0.6; p = 0.002) were lower in the study group compared to control group. Postoperative cortisol levels in both groups were higher than the preoperative, but no significant difference was found. The study group showed higher values for BETA and IS. Percentage changes between the groups were significant for all parameters.

Conclusion: Pre-operative caloric load (amino acids) reduces the level of insulin resistance and glucose in the presence of elevated cortisol levels.
