Addition of sufentanil to bupivacaine in caudal block effect on stress responses in children

BACKGROUND: The aim of the present randomized study was to determine the effect of adding sufentanil to bupivacaine, compared with bupivacaine alone in caudal block, on the surgical stress response in children. METHODS: The children were premedicated with midazolam 0.5 mg/kg. All children received induction with nitrous oxide and sevoflurane. Anesthesia was maintained with the same volatile agents in the both groups. The children were randomly allocated to two groups. Group I received bupivacaine alone (n = 17) and group II received bupivacaine + sufentanil (n = 16). Caudal block was performed with 0.25% bupivacaine 2 mg/kg (group I) or 0.25% bupivacaine 2 mg/kg with sufentanil 0.5 microg/kg (group II) after induction of anesthesia. Blood samples were obtained after induction of anesthesia (T(0)) to measure baseline concentrations of cortisol, prolactin, glucose and insulin. Additional samples were obtained 30 min after the start of surgery (T(1)), and 60 min after the end of surgery (T(2)). RESULTS: All of the basal values (T(0)) were within the normal ranges of the authors' laboratory for children of this age group and there were no differences between the groups (P > 0.05). In both groups, glucose concentration increased at T(1), compared with T(0) and T(2) (P < 0.05). The glucose concentration was unchanged at T(2) compared with T(0) in both group (P > 0.05). In both groups, prolactin concentration increased at T(1), compared with T(0) and decreased at T(2), compared with T(1) (P < 0.05). Cortisol decreased at T(1) and T(2), compared with T(0) in both groups. (P < 0.05). Insulin concentration remained unchanged at T(0) and T(2), but increased slightly at T(1) in both groups (P > 0.05). There were no significant differences in plasma prolactin, cortisol, glucose and insulin levels between the two groups at T(1) and T(2) (P > 0.05). CONCLUSION: There is no advantage in adding 0.5 microg/kg sufentanil to bupivacaine over bupivacaine alone in the caudal block, with regard to the surgical stress response in children.     

Short-term subjective efficacy of doxazosin in predicting probability of prostatectomy in the management of benign prostatic hyperplasia in patients with severe symptoms

BACKGROUND: The severity of symptoms still constitutes the major indication for transurethral prostatectomy, despite the extensive utilization of medical treatments. The aim of the study presented here was to investigate the impact of doxazosin on symptoms in relation to the probability of consequent surgery in severely symptomatic patients. METHODS: Patients with an International Prostate Symptom Score (IPSS) between 18 and 35 were included in the study. The patients received 4 mg/day doxazosin, and subjective efficacy was assessed by IPSS at the first and third months. In addition, the patients were classified at the third month according to a single question regarding satisfaction with medical treatment in terms of symptom relief as 'ineffective, no change, and effective'. RESULTS: A total of 178 patients constituted the study group. Mean total symptom scores were 24, 19 and 17 at baseline, first and third months, respectively (P < 0.05). According to results of the questionnaire, 23% of the patients claimed the treatment was ineffective, and subsequently, the majority of this group (93%) underwent prostatectomy in a year. In addition, 33% of the patients reported no change in their symptoms, while 44% reported that the medication was effective. However, after 1 year, 59% and 15% of these cases underwent surgical treatment, respectively. The probability of surgery in the 'ineffective' group was significantly higher compared to the remaining groups (P < 0.05). CONCLUSION: The majority of patients with severe symptoms who were not satisfied with the medication at the 3rd month underwent surgery. This observation may provide a predictor for subsequent probability of prostatectomy. Therefore, reassessment of patients would be a cost-effective approach for the treatment of BPH in severely symptomatic patients.     

Impact of frailty and ultrasonography-based sarcopenia on the development of postoperative complications in gastrointestinal cancer patients

Background/aim Gastrointestinal (GI) system cancers are frequent among older adults and it is still difficult to predict which are at increased risk for postoperative complications. Frailty and sarcopenia are increasing problems of older population and may be associated with adverse outcomes. In this study we aimed to examine the effect of sarcopenia and frailty on postoperative complications in older patients undergoing surgery for GI cancers.Materials and methods Forty-nine patients admitted to general surgery clinic with the diagnosis of gastrointestinal system cancers were included in this cross-sectional study. Frailty status was assessed using the Edmonton Frail Scale (EFS). Sarcopenia was defined due to the EWGSOP2 criteria and ultrasonography was used to evaluate muscle mass.Results The median age of the patients was 70 (min-max: 65–87). Fourteen (28.6%) patients were found to be sarcopenic and 16 (32.7%) patients were frail, and 6 (37.5%) of these patients were also severe sarcopenic (p = 0.04). When the postoperative complications were assessed, time to oral intake, time to enough oral intake, length of hospital stay in the postoperative period were found to be longer in frail patients (p = 0.02, p = 0.03, p = 0.04 respectively). Postoperative complications were not different due to the sarcopenia.Conclusion Frailty, but not sarcopenia was associated with adverse outcomes in older adults undergoing GI cancer surgery. Comprehensive geriatric assessment before surgical intervention may help to identify patients who are at risk.     

Permanent Pacemaker Implantation in a Pregnant Woman with the Guidance of ECG and Two-Dimensional Echocardiography

A 30-year-old pregnant woman was admitted to the Cardiology Research Center with syncope, dizziness, and fatigue on exertion. On ECG complete atrioventricular block was diagnosed. Permanent pacemaker implantation was performed with the guidance of ECG and two-dimensional echocardiography and without the use of fluoroscopy.
