Importance of the National Early Warning Score (NEWS) at the time of discharge from the intensive care unit

Backround/aim: To identify, at an early stage of intensive care, patients who will require readmission to the intensive care unit (ICU) based on their National Early Warning Score (NEWS-d) at discharge. Materials and methods: Overall, 536 patients aged >18 years who stayed at a tertiary ICU for >24 h were included. Patients who readmitted and not readmitted to the intensive care within 48 h after discharge were compared. Results: Mean patient age was 64.26 ± 18.50 years and 252 (44.7%) patients were male. Mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 21.86 ± 8.74; mean NEWS-d was 4.48 ± 2.53. Forty-nine (9.1%) were readmitted to ICU. The reasons for initial admission, age, and NEWS-d vvalues were significantly different between the 2 groups. The NEWS-d values of the readmitted group were significantly higher (9.16 ± 1.05) than nonreadmitted group (4.01 ± 2.13). Based on receiver operation curve analysis, sensitivity and specificity were 98% and 95%, respectively, considering a NEWS-d cut-off value of 7.5 as the limit value for estimating readmission. Conclusion: A NEWS-d value of >7.5 demonstrated high sensitivity and specificity in identifying the risk of readmission for patients being discharged from ICU.

The effect of atropine in preventing catheter-related pain and discomfort in patients undergoing transurethral resection due to bladder tumor; prospective randomized, controlled study.

BACKGROUND: Catheter-related bladder discomfort (CRBD) has been observed in many patients undergoing a urethral catheterization. CRBD may be so severe that the patients require additional analgesics. Muscarinic receptors are involved in the mechanism of CRBD. The aim of this study is to determine the effects of the antimuscarinic properties of atropine, which is frequently used in current practice on CRBD, by comparing it with sugammadex which has no antimuscarinic effects. METHODS: Sixty patients selected for transurethral resection due to bladder tumors were randomized into 2 groups: an atropine group and a sugammadex group, with no antimuscarinic effect. The patients were given rocuronium (0.6 mg/kg) as a neuromuscular- blocker. In addition to the frequency and severity of CRBD postoperatively at 0, 1, 6, 12, and 24 hours, postoperative numeric rating scale (NRS) scores, and postoperative nausea and vomiting were examined. RESULTS: The incidence of CRBD was significantly lower in the atropine group in all postoperative measurements. The score was found to be significantly lower in the atropine group when NRS measurements were performed at all time periods (P < 0.01). There was no difference between the groups in terms of nausea and vomiting (P > 0.05). CONCLUSIONS: Atropine is a cheap, easy-to-access, safe-to-use drug for reducing CRBD symptoms, without any observed adverse effects. Since it not only reduces CRBD symptoms but also has a positive effect on postoperative pain, it can be used safely to increase patient comfort in patients receiving general anesthesia and a urinary catheter.

Comparison of the Effects of Neostigmine and Sugammadex on Colonic Anastomotic Strength in Rats.

BACKGROUND: After colorectal surgery, anastomotic leakage is a major cause of mortality and morbidity. There are many factors affecting anastomotic leakage. It is known that agents such as neostigmine that is used to reverse neuromuscular blockade have certain effects on anastomosis. In our study, in which we planned to test this hypothesis, we aimed to compare the possible effects of different doses of sugammadex and neostigmine on colon anastomosis strength in a colonic resection anastomosis model in rats. MATERIALS AND METHODS: Forty adult Wistar albino male rats were divided into five groups as control (group C), Sugammadex 16 mg/kg (group SL), sugammadex 96 mg/kg (group SH), neostigmine 0.3 µmol/kg (group NL), and neostigmine 1.5 µmol/kg (group NH). The transverse colons of all rats were resected, and colonic anastomosis was performed. Appropriate drug doses according to the groups were given on the postoperative seventh day, and tissue hydroxyproline (TH) level and anastomotic bursting pressure were measured. RESULTS: Anastomotic bursting pressure values were statistically significantly different between the groups (P = 0.001). The bursting pressure in group SH was significantly higher compared with group C, group NL, and group NH. The hydroxyproline values were statistically significantly different between the groups (P = 0.015). According to the post hoc test results, the difference was between group SH and group C (P = 0.007). There were no significant differences between the other groups (P > 0.05). There was no significant difference in terms of intra-abdominal adhesion rates between the groups. CONCLUSIONS: In our study, we found that low and high doses of neostigmine had no variable effect on anastomosis, but high dose of sugammadex (96 mg/kg) had an increasing effect on intestinal anastomosis strength.

Comparison of the effects of continuous versus intermittent enteral feeding on plasma leptin and ghrelin levels in Intensive Care Units / Comparação do efeito da alimentação enteral contínua com o efeito da alimentação intermitente nos níveis plasmáticos de leptina e grelina em Unidades de Terapia Intensiva

ABSTRACT Objective: The aim of this prospective randomized trial is to verify whether there is an association between the methods of administration of enteral nutrition and the leptin and ghrelin hormones, which have a major role in the regulation of energy metabolism. Methods: This study enrolled 38 enteral-fed patients aged 18 to 85 in the Intensive Care Unit. The patients were prospectively randomized to receive either continuous infusion (n=19) or intermittent feeding (n=18) of enteral nutrition. In addition to routine biochemical assays, blood samples were taken from the patients for leptin and ghrelin analyses on the 1th, 7th, and 14th days of enteral nutrition. Results: There was no statistically significant difference between the groups regarding descriptive statistics and categorical variables such as underlying diseases, complications, steroid use and others (p>0.05). The decrease in the number of white blood cells and in creatinine and C-reactive protein levels over time were statistically significant (p=0.010, p=0.026, p<0.001 respectively). There was no statistically significant difference between the groups with respect to leptin and ghrelin levels (p=0.982 and p=0.054). Leptin levels did not change over time; however, the ghrelin levels of both groups were significantly higher on the 7th and 14th days than on the first day of analysis (p=0.003). Conclusion: This study revealed that both continuous and intermittent enteral nutrition feeding regimens were well tolerated in Intensive Care Unit patients showing minor complications. The method of administration of enteral nutrition alone did not affect the leptin and ghrelin levels. Randomized controlled large cohort trials are needed to to compare intermittent and continuous enteral nutrition to determine which one is more adaptable to diurnal patterns of secretion metabolic hormones.

RESUMO Objetivo: Este ensaio aleatório prospectivo tem por objetivo verificar se existe uma associação entre o programa de administração de nutrição enteral e os hormonios leptina e grelina, os quais funcionam no metabolismo energético. Métodos: Este estudo incluiu 38 pacientes de Unidades de Terapia Intensiva, com idades entre os 18 e os 85 anos, que receberam nutrição enteral. Os pacientes foram escolhidos aleatoriamente para receberem nutrição enteral utilizando infusão contínua (n=19) ou intermitente (n=18). Além de exames bioquímicos de rotina, foram colhidas amostras de sangue dos pacientes para análises dos níveis de leptina e grelina no 1º, 7º e 14º dias de nutrição enteral. Resultados: Não houve diferença estatística significante entre os grupos em relação a dados descritivos e variáveis categóricas tais como doenças subjacentes, complicações, utilização de esteroides e outros (p>0,05). A diminuição no número de leucócitos e nos níveis de creatinina e proteína C-reativa com o tempo foi estatisticamente significativa (p=0,010, p=0,026, p<0,001, respetivamente). Não existiu diferença com significância estatística entre os grupos em relação aos níveis de leptina e grelina (p=0,982 e p=0,054). Embora os níveis de leptina não mudaram com o tempo, os níveis de grelina de ambos os grupos foram significativamente superiores no 7° e 14° dias quando comparados aos verificados na análise do primeiro dia (p=0,003). Conclusão: Este estudo revelou que os programas de nutrição enteral contínua e intermitente foram bem tolerados com pequenas complicações apresentadas pelos pacientes em Unidades de Terapia Intensiva. O padrão de administração de nutrição enteral por si só não afetou os níveis de leptina e grelina. Estudos controlados aleatórios em coortes maiores são necessários para verificar qual programa de administração de nutrição enteral, intermitente ou a contínuo, é mais adaptável ao padrão de secreção diurno de hormônios metabólicos.

Comparison of preventive analgesia techniques in circumcision cases: Dorsal penile nerve block, caudal block, or subcutaneous morphine?

OBJECTIVE: To compare 3 different techniques of preventive analgesia before circumcision operations in male children between 6-12 years of age. Our objective was to investigate the duration and quality of postoperative analgesia in patients, who were subject to caudal block technique, dorsal penile nerve block or who were administered subcutaneous morphine. METHODS: The prospective, randomised, single-blind study was conducted at Ordu University Training and Research Hospital, Ordu, Turkey, from January 1 to June 30, 2015, and comprised boys aged 6-12 years, who were scheduled to undergo circumcision operation. All patients were under general anaesthesia by means of laryngeal masks. The patients were randomised into 3 equal groups. The patients in Group C received caudal block with bupivacaine 0.25% in a total volume of 0.50 ml/kg in lateral position. Those in Group M received injections of 100 mcg/kg of subcutaneous morphine into the deltoid muscle. Patients in Group DP were subjected to dorsal penile nerve block with 1 mg/kg of bupivacaine 0.25%. Intraoperative haemodynamic data, pain and sedation scores, according to Children's Hospital of Eastern Ontorio Pain Scale and Ramsay Sedation Scale, were recorded at postoperative 1st, 6th and 24th hours in all cases. RESULTS: The 60 subjects in the study were divided into 3 groups of 20(33.3%) each. The overall mean age was 7.75±8.12 years. At 1 hour after surgery; 8(40%) cases in Group M, 5(25%) cases in Group DP, and all the 20(100%) cases in Group C had a pain score <6 (p<0.05). When the scores were analysed 12 hours post-operatively, 5(25%) cases in Group M and 10(50%) cases in Group DP had a pain score >6, while the pain scores of all the 20(100%) cases in Group C were <6 (p<0.01). Among the groups, there was no statistically significant difference regarding the sedation scores (p>0.05). CONCLUSIONS: Using the three methods, analgesia lasted until 12 hours postoperatively, being more evident in the caudal block group, minimising postoperative stress in children and parents.

Comparison of the effects of sugammadex and neostigmine on postoperative nausea and vomiting.

BACKGROUND AND OBJECTIVES: The aim of our study is to compare the effects of sugammadex and neostigmine, used for neuromuscular blockage antagonism, on postoperative nausea and vomiting (PONV). METHODS: Our study was completed with 98 ASA I-II risk patients undergoing endotracheal intubation under general anesthesia. At the end of the surgery patients were randomly divided into two groups given 2mgkg-1 sugammadex (Group S) or 50µgkg-1 neostigmine plus 0.2mgkg-1 atropine (Group N). Monitoring and recording times were set as 1 hour postoperative and from 1-6, 6-12, and 12-24hours. The anti-emetic amounts administered were recorded. RESULTS: In the first hour postoperative 13 patients in Group N (27%) and 4 in Group S (8%) were observed to have nausea and/or vomiting and the difference was statistically significant (p=0.0016). During the 24 hours of monitoring there was no significant difference in the incidence and severity of PONV (p>0.05), however the number of patients given ondansetron for PONV treatment in Group N was statistically significantly higher than the number in Group S (16 in Group N, 6 in Group S, p<0.011). CONCLUSIONS: At the end of our study comparing neostigmine with sugammadex for neuromuscular blockage antagonism, we found use of sugammadex had lower incidence of PONV in the postoperative 1st hour and less anti-emetic use in 24 hours of monitoring.

Anesthesia in a patient with Stiff Person Syndrome / Anestesia em paciente com síndrome da pessoa rígida

Abstract Stiff Person Syndrome (SPS), typified by rigidity in muscles of the torso and extremities and painful episodic spasms, is a rare autoimmune-based neurological disease. Here we present the successful endotracheal intubation and application of TIVA without muscle relaxants on an SPS patient. A 46 years old male patient was operated with ASA-II physical status because of lumber vertebral compression fracture. After induction of anesthesia using lidocaine, propofol and remifentanil tracheal intubation was completed easily without neuromuscular blockage. Anesthesia was maintained with propofol, remifentanil and O2/air mixture. After a problem-free intraoperative period the patient was extubated and seven days later was discharged walking with aid. Though the mechanism is not clear neuromuscular blockers and volatile anesthetics may cause prolonged hypotonia in patients with SPS. We think the TIVA technique, a general anesthetic practice which does not require neuromuscular blockage, is suitable for these patients.

Resumo A síndrome da pessoa rígida (SPR), caracterizada pela rigidez dos músculos do tronco e das extremidades e por episódios de espasmos dolorosos, é uma doença neurológica autoimune rara. Apresentamos o ocaso de intubação endotraqueal bem-sucedida e aplicação de AVT sem relaxantes musculares em um paciente com SPR. Paciente do sexo masculino, 46 anos, estado físico ASA-II, submetido à cirurgia devido à fratura por compressão da coluna lombar. Após a indução da anestesia com lidocaína, propofol e remifentanil, a intubação traqueal foi concluída com facilidade, sem bloqueio neuromuscular. A anestesia foi mantida com propofol, remifentanil e mistura de ar/O2. Após o período intraoperatório, que transcorreu sem intercorrências, o paciente foi extubado e, sete dias depois, recebeu alta, deambulando com ajuda. Embora o mecanismo não esteja claro, bloqueadores neuromusculares e anestésicos voláteis podem causar hipotonia prolongada em pacientes com SPR. Acreditamos que a técnica de AVT, uma prática de anestesia geral que não requer bloqueio neuromuscular, é adequada para esses pacientes.

A comparison of different densities of levobupivacaine solutions for unilateral spinal anaesthesia / Uma comparação das diferentes densidades das soluções de levobupivacaína para raquianestesia unilateral

ABSTRACT BACKGROUND AND OBJECTIVES: The aim of the study was to compare the block characteristics and clinical effects of dextrose added to levobupivacaine solutions at different concentrations to provide unilateral spinal anaesthesia in lower extremity surgery. METHODS: This prospective, randomised, double-blind study comprised 75 ASA I-II risk patients for whom unilateral total knee arthroscopy was planned. The patients were assigned to three groups: in Group I, 60 mg dextrose was added to 7.5 mg of 0.5% levobupivacaine, in Group II, 80 mg and in Group III, 100 mg. Spinal anaesthesia was applied to the patient in the lateral decubitus position with the operated side below and the patient was kept in position for 10 min. RESULTS: The time for the sensorial block to achieve T12 level was slower in Group I than in Groups II and III (p < 0.05, p< 0.00). The time to full recovery of the sensorial block was 136 min in Group I, 154 min in Group II and 170 min in Group III. The differences were statistically significant (p < 0.05). The mean duration of the motor block was 88 min in Group I, 105 min in Group II, and 139 min in Group III and the differences were statistically significant (p < 0.05). The time to urination in Group I was statistically significantly shorter than in the other groups (p < 0.00). CONCLUSIONS: The results of the study showed that together with an increase in density, the sensory and motor block duration was lengthened. It can be concluded that 30 mg mL-1 concentration of dextrose added to 7.5 mg levobupivacaine is sufficient to provide unilateral spinal anaesthesia in day-case arthroscopic knee surgery.

RESUMO JUSTIFICATIVA E OBJETIVOS: Comparar as características do bloqueio e os efeitos clínicos da adição de dextrose às soluções de levobupivacaína em diferentes concentrações para proporcionar raquianestesia unilateral em cirurgia de extremidade inferior. MÉTODOS: Estudo prospectivo, randômico e duplo-cego conduzido com 75 pacientes, estado físico ASA I-II, programados para artroplastia unilateral total do joelho. Os pacientes foram divididos em três grupos: no Grupo-I, 60 mg de dextrose foram adicionados a 7,5 mg de levobupivacaína a 0,5%; no Grupo II, 80 mg e no Grupo III, 100 mg. A raquianestesia foi aplicada ao paciente posicionado em decúbito lateral, com o lado operado abaixo, e o paciente foi mantido em posição durante 10 minutos. RESULTADOS: O tempo para o bloqueio sensorial atingir o nível T12 foi mais lento no Grupo-I do que nos grupos II e III (p < 0,05,p < 0,00). O tempo de recuperação total do bloqueio sensorial foi de 136 minutos no Grupo-I, 154 minutos no Grupo-II e 170 minutos no Grupo III. As diferenças foram estatisticamente significativas (p < 0,05). A média da duração do bloqueio motor foi de 88 minutos no Grupo-I, 105 minutos no Grupo-II e 139 minutos no Grupo-III e as diferenças foram estatisticamente significativas (p< 0,05). O tempo de micção foi significativamente menor no Grupo-I do que nos outros grupos (p < 0,00). CONCLUSÕES: Os resultados do estudo mostraram que, junto com um aumento da densidade, a duração dos bloqueios sensorial e motor foi prolongada. Pode-se concluir que uma concentração 30 mg mL-1 de dextrose adicionada a 7,5 mg de levobupivacaína é suficiente para proporcionar raquianestesia unilateral para artroscopia do joelho em regime ambulatorial.

Haemodynamic Responses to Tracheal Intubation Using Propofol, Etomidate and Etomidate-Propofol Combination in Anaesthesia Induction.

INTRODUCTION: The aim of this study was to measure the haemodynamic responses to a etomidate-propofol combination used for anaesthesia induction and to compare the haemodynamic responses with the separate use of each drug. METHODS: The patients were randomly divided into three groups as group P (n = 30, propofol 2.5 mg kg(-1)), group E (n = 30, etomidate 0.3 mg kg(-1)) and group PE (n = 30, propofol 1.25 mg kg(-1) + etomidate 0.15 mg kg(-1)). For each patient, the times of measurement of the heart rate (HR) and mean arterial pressure values were defined as baseline, after the induction, before the intubation, immediately after the intubation and 1, 2, 3, 4, 5 and 10 minutes after the intubation. RESULTS: In all 3 groups, a significant decrease in MAP values were seen at T2 and T3 compared to the baseline values, and this decrease was greater in group P compared to that in group E and PE (P < 0.001, P < 0.01). A significant increase was seen in all 3 groups in the mean arterial pressure (MAP) value at T4 after the intubation. When the groups were compared with each other, this increase was greater in group E than in the other two groups (with group P, P < 0.001; with group PE, P < 0.01). CONCLUSION: Etomidate-propofol combination may be a valuable alternative when extremes of hypotensive and hypertensive responses due to propofol and etomidate are best to be avoided.

Intraocular pressure changes associated with tracheal extubation: Comparison of sugammadex with conventional reversal of neuromuscular blockade.

OBJECTIVE: To compare the effects of neostigmine/atropine combination and sugammadex on intraocular pressure during tracheal extubation period. METHODS: The single-blind prospective randomised controlled study was conducted at Ordu University Research and Training Hospital from August to October 2014, and comprised patients who were randomly assigned to 2 groups according to the agent used for reversal of neuromuscular blockade. Group N received 0.05mgkg-1 neostigmine and 0.02 mgkg-1 atropine and the patients in Group S received 2mgkg-1 sugammadex intravenously. Heart rate, mean arterial pressure and intraocular pressure were measured at baseline, before the induction (T1), after the application of reversal agent (T2), and 1 (T3), 3 (T4), 5 (T5) and 10 (T6) minutes after the extubation. SPSS 16 was used for statistical analysis. RESULTS: There were 36 patients in the study; 18(50%) in each group. There was no significant difference between the groups in terms of age, gender and body mass index (p>0.05 each). Intraocular pressure was significantly higher when the baseline level was compared with all measurement intervals in Group N (p<0.05 each). In Group S, it showed no significant difference at T2 (p>0.05) whereas it was significantly higher at all other measurement intervals (p<0.05 each). Intergroup comparisons showed statistically significant difference in heart rate and mean arterial pressure levels at T2 interval which were higher in Group N (p<0.01). Intraocular pressure levels at T2 and T3 intervals were significantly higher in Group N (p<0.01). CONCLUSIONS: Lower end-extubation intraocular pressure levels were obtained when sugammadex was used as a neuromuscular block reversal agent in comparison with neostigmine-atropine combination. Sugammadex may be a better option for the reversal of neuromuscular blockade and intraocular pressure increase should be avoided in patients with glaucoma or penetrating eye injury.

Effect of Sugammadex on Postoperative Bleeding and Coagulation Parameters After Septoplasty: A Randomized Prospective Study.

BACKGROUND: Sugammadex is a reversal agent with well known advantages but it's effects on haemostasis and bleeding have been a topic of interest. Septoplasty is a common surgical procedure with postoperative respiratory complications and bleeding. The aim of this study is to investigate the effects of sugammadex on postoperative coagulation parameters and bleeding after septoplasty procedure. MATERIAL AND METHODS: In this randomized controlled study, fifty patients were grouped into two groups; neostigmine (Group N) vs. sugammadex (Group S). For the evaluation of PT, aPTT and INR, blood samples were taken for at the postoperative 120th minutes and alteration of these values with respect to preoperative values were documented. Postoperative bleeding was measured by evaluating the amount of blood absorbed on the nasal tip dressing during 3 hours postoperatively. RESULTS: Postoperative bleeding amount was significantly higher in the Group S compared to Group N (p=0.013). No significant difference was observed between two groups according to coagulation parameters (PT; p=0.953, aPTT; p=0.734, INR; p=0.612). CONCLUSIONS: Sugammadex was associated with higher amount of postoperative bleeding than neostigmine in septoplasty patients. In surgical procedures having high risk of bleeding the safety of sugammadex need to be verified.

A Retrospective Analysis of Comparison of General Versus Regional Anaesthesia for Endovascular Repair of Abdominal Aortic Aneurysm.

OBJECTIVE: The aim of this study is to compare general anaesthesia (GA) versus regional anaesthesia (RA) for endovascular aneurysm repair (EVAR). METHODS: We analysed the files of 89 patients between August 2010-August 2012 who underwent elective EVAR retrospectively. RESULTS: We performed RA for 32 patients (36%) and GA for 57 patients (64%). The operations were completed successfully in both groups and did not require conventional surgery. The mean age of the patients was 71.5±7 (range 50-88 years). RA was preferred more than GA in the presence of advanced-stage chronic obstructive pulmonary disease statistically (p=0.032). The usage of vasodilator drug and atropine was found to be higher in the GA group than the RA group in the intraoperative period (p=0.001 and p=0.01, respectively). The intensive care unit (ICU) was necessary for 5 patients in the RA group (16%) and 13 patients for the GA group (23%) postoperatively (p=0.301). The median ICU stay in the RA group was 2 hours and 4.4 hours in the GA group (p=0.114). The median hospital stay was 2.63±1.91 days in the RA group and 2.04±1.16 days in the GA group, with no statistically significant difference between groups (p=0.120). There was no mortality of patients in either group for the peroperative period and the 30-day follow-up period. CONCLUSION: Our present study suggests that patient characteristics are more important than the anaesthetic method on the outcomes of EVAR.

Comparison of Dexmedetomidine Versus Ketamine-Propofol Combination for Sedation in Cataract Surgery.

OBJECTIVE: The aim of this study is to compare the sedative properties and haemodynamic and respiratory effects of dexmedetomidine and a ketamine-propofol combination (ketofol), which are expected to have minimal effects on spontaneous breathing. METHODS: Sixty patients were enrolled in this prospective randomised study. Patients were divided into 2 groups according to the administration of dexmedetomidine (Group D) and ketofol (Group K). Target sedation level was determined as a Ramsay Sedation Score of 3. In Group D, 0.5 mcg kg(-1) dexmedetomidine was administered via intravenous route in 10 minutes versus 0.125 mL kg(-1) of a solution containing 200 mg propofol and 100 mg ketamine in Group K. Haemodynamic and respiratory effects, postoperative awakening time, analgesic properties and satisfaction levels of the patients and surgeon were assessed. RESULTS: There was a statistically significant decrease in mean arterial pressures following drug administration compared to initial measurements in both groups. However, there was a statistically significant decrease in heart rate only in Group D. There was no significant difference between the two groups regarding respiratory rate and protection of spontaneous respiration. Although the time for Aldrete score to be 9 was 16.1 minutes for Group K, it was 24.9 minutes for Group D, and this difference was statistically significant (p<0.01). There was no significant difference between the two groups regarding adverse effects, pain scores and satisfaction levels of the patients and surgeon. CONCLUSION: Compared to dexmedetomidine, at similar sedation levels, sedation provided by ketofol enables satisfactory analgesia. Moreover, ketofol has a more rapid onset of action and a shorter recovery period from anaesthesia without causing significant haemodynamic or respiratory adverse effects.

Continuous Spinal Anaesthesia for Endovascular Repair of Abdominal Aortic Aneurysm in High-Risk Patient.

Endovascular aneurysm repair (EVAR) is increasingly being used in abdominal aortic aneurysm (AAA) treatment, as it is less invasive than open surgery. A wide range of anaesthetic types, such as general anaesthesia, neuroaxial blocks and local anaesthesia, have been shown to be appropriate for the EVAR procedure. In the continuous spinal anaesthesia (CSA) method, the local anaesthetic may be titrated through a catheter placed in the subarachnoid space, allowing better control of the anaesthetic level and a reduction in potential haemodynamic side effects. Our aim is to present CSA as a successful anaesthetic technique for EVAR in an AAA patient with severe co-existing diseases.

Comparison of levobupivacaine alone and in combination with fentanyl and sufentanil in patients undergoing transurethral resection of the prostate.

BACKGROUND: It was aimed to compare the efficacy and adverse effects of levobupivacaine alone and in combination with fentanyl and sufentanil during transurethral resection of the prostate (TURP) under spinal anesthesia. MATERIALS AND METHODS: In this prospective, randomized, double-blind trial, 60 patients undergoing elective TURP under spinal anesthesia were randomized into three groups. Ten milligrams of 0.5% levobupivacaine in Group-I, 7.5 mg 0.5% levobupivacaine combined with 25 µg fentanyl in Group-II and 7.5 mg 0.5% levobupivacaine with 2.5 µg sufentanil in Group-III were administered intrathecally. RESULTS: The time for sensorial block to reach level T10 was 10.2 ± 2.0, 6.9 ± 1.7 and 7.0 ± 1.4 min in Group-I, II and III, respectively (P < 0.001). The maximum sensorial block level was T8 in all groups. The frequency of a complete motor block was higher in Group-I. The mean duration of motor block was shorter in Group-II and III than in Group-I (P < 0.001). There were no differences between groups regarding side effects (P > 0.05). The time for first analgesic request was shorter in Group-I than in the other two groups (P < 0.05). During the first postoperative 24-h period, 11 (58%) patients in Group-I, 9 (48%) patients in Group II and 9 (45%) patients in Group-III required an analgesic drug (P > 0.05). CONCLUSION: This study showed that combining lower dose levobupivacaine with fentanyl and sufentanil provides faster onset of sensorial block, lower frequency and shorter duration of motor block, and longer analgesia time in TURP under spinal anesthesia.
