RESUMO
BACKGROUND: Perioperative hemodynamic fluctuations are seen more often in hypertensive patients than in normotensive patients. The purpose of our study was to investigate the perioperative hemodynamic effects of dexmedetomidine and midazolam used for premedication in hypertensive patients relative to each other and in comparison to normotensive patients. METHODS: One-hundred-forty female, normotensive or hypertensive patients undergoing myomectomies or hysterectomies. They were randomly enrolled into the subgroups: Group ND (normotensive-dexmedetomidine); Group HD (hypertensive-dexmedetomine); Group NM (normotensive-midazolam); Group HM (hypertensive- midazolam). Dexmedetomidine was administered at a concentration of 0.5 µg.kg(-1), and midazolam was administered at a concentration of 0.025 µg.kg(-1) via intravenous (IV) infusion before the induction of anaesthesia. Haemodynamic parameters were recorded at several times (T(beginning), T(preop5 min), T(preop 10 min), T(induction), T(intubation), T(intubation 5 min), T(initial surgery), T(surgery 15 min), T(surgery 30 min), T(extubation), T(extubation 5 min)). Propofol amount for induction, time between induction and initial surgery, demand of antihypertensive therapy, rescue atropine were recorded. Quantitative clinical and demographic characteristics were compared using One Way ANOVA. The values were compared using One-way Analysis of Variance. Additionally periodic variations were examined by One way Repeated Measures Analysis of Variance for groups separately. RESULTS: SBP was significantly different between normotensive and hypertensive groups at the following time points: T(preop 5 min), T(preop 10 min), T(induction), T(intubation), T(intubation 5 min) and T(initial surgery). MBP was significantly different in the hypertensive groups at T(induction), T(intubation), T(intubation 5 min), T(initial surgery), T(surgery 15 min), T(surgery 30 min), T(extubation) and T(extubation 5 min). The perioperative requirements for antihypertensive drugs were significantly higher in Group HM. CONCLUSION: In the hypertensive patients, dexmedetomidine premedication provides better hemodynamic stability compared with midazolam, and because it decreases the antihypertensive requirements, its use might be beneficial.

BACKGROUND AND AIMS: The effect of local anesthetics on myometrial contractility during labor analgesia is debatable. We aimed to compare the effects of bupivacaine and levobupivacaine on rat uterine contractility in an in vivo setting. METHODS: Electrical activities of 40 pregnant rat uteruses were recorded on electrohysterogram after dividing the rats into bupivacaine and levobupivacaine groups. Uterine contraction frequencies were recorded at each 5-min interval. The first 5-min recording was considered the control, which was immediately followed by intramyometrial administration of either bupivacaine or levobupivacaine. The recordings were continued for 30 min. The changes in frequencies at each time interval of the groups were compared with each other and the control recording. RESULTS: The frequencies from both groups at each interval were lower than the control values, but not different between the groups. The frequencies of the bupivacaine group during the 5-10 min and 10-15 min intervals were lower than the control time interval, but no significant differences were present between the control and the other time intervals. However, no significant differences were found at any time interval for the levobupivacaine group. CONCLUSION: Levobupivacaine led to less muscle relaxation compared to bupivacaine and may be a better option for labor analgesia and anesthesia considering uterine contractility.

Probiotics which are non-pathogenic live microorganisms ingested along with food or as dietary supplements, are thought to be beneficial to the host by supporting the microbial balance in digestive system. Various studies suggest that the effects of probiotics on the intestinal mucosa and immunity are protective against bacterial translocation. We aimed to investigate bacterial translocation related to the amount of CO2 insufflation given during laparoscopy and the effect of probiotic bacteria in an experimental peritonitis model. In this study 60 Wistar rats were used in six groups consisting of 10 rats. Group 1, 3 and 5 consisted of the rats that were fed without probiotics, while the rats in Group 2, 4, and 6 were fed with water containing 5 x 108 cfu/ml probiotic bacteria complex (Bifidobacterium lactis, Lactobacillus bulgaricus, Streptococcus thermophilus) for 15 days. To generate experimental peritonitis, 2 x 107 cfu/ml Escherichia coli ATCC 25922 was inoculated intraperitoneally to all of the rats. Thereafter, laparoscopy was applied in all groups. Application in Group 1 and Group 2 was without CO2; Group 3 and Group 4 with 14 mmHg CO2 insufflation, and Group 5 and Group 6 with 20 mmHg CO2 insufflation. Blood samples were taken in 2nd, 4th, and 6th hours. Mesenteric lymph node, liver and spleen samples were taken at 6th hour when the rats were sacrificed and then these were evaluated microbiologically with qualitative and quantitative methods. Bacterial translocation and bacteremia were found in the rats that were undergone experimental peritonitis during laparoscopy. All positive tissue and blood cultures yielded E.coli. The highest level of bacterial translocation was found to be in mesenteric lymph nodes (in 3/10, 6/10 and 10/10 in groups 1, 3 and 5 fed without probiotics, respectively; in 2/10, 3/10 and 4/10 in groups 2, 4 and 6 fed with probiotics, respectively). The bacterial translocation rates were found to be related to the increased CO2 insufflation. It was found that probiotic bacteria were more effective for decreasing bacterial translocation rates and bacteremia in the groups that were given high CO2 pressure during laparoscopy. It was also found that these results were correlated with bacterial translocation per gram of tissue. As an example, the quantitative bacterial growth values detected in mesenteric lymph node were 5.4 ± 2.9 x 103, 10.6 ± 3.3 x 103 and 21.5 ± 12.4 x 103 cfu/g in groups 1, 3 and 5, fed without probiotics, respectively; and 2.0 ± 1.3 x 103, 3.8 ± 1.9 x 103 and 9.0 ± 3.1 x 103 cfu/g in groups 2, 4 and 6, fed with probiotics, respectively. Our data emphasized that probiotic bacteria may be used as prophylactic agents for the prevention of bacterial translocation during laparoscopy, however comprehensive and clinical studies are needed to support these experimental results.

OBJECTIVES: We aimed to evaluate the effects of dexmedetomidine hydrochloride (DEX) on hemodynamic parameters and on surgeon and patient satisfaction during functional endoscopic sinus surgery (FESS). METHODS: Forty patients who were to undergo FESS were enrolled in this randomized, prospective, controlled study. In the DEX group, conscious sedation was induced with an infusion of 1 microg/kg of DEX 10 minutes before surgery, followed by an infusion of DEX at 0.2 microg/kg per hour. A control group was given identical amounts of saline solution. During the procedure, hemodynamic data were recorded. The patients evaluated their pain on a visual analog scale (VAS). Intraoperative bleeding was rated on a 6-point scale for evaluation of operative field visibility. RESULTS: We observed that the DEX group had lower bleeding scores (p = 0.019). The heart rates were lower in the DEX group at the time of induction (p = 0.052) and in the 1st (p = 0.009) and 20th minutes (p = 0.039) of induction. The mean blood pressure values were lower in the DEX group in the 5th (p < 0.001), 45th (p = 0.003), and 60th (p = 0.05) minutes of induction. The VAS score was lower in the DEX group in the 30th postoperative minute (p = 0.001); however, the VAS score was lower in the control group after the 12th hour (p < 0.001). Postoperative side effects such as nausea, tachycardia, hypotension, and vomiting were significantly less frequent in the DEX group (p < 0.001). CONCLUSIONS: We observed that the intraoperative bleeding, hemodynamic stability, and VAS scores were better and the side effects were less frequent in the DEX group.

PURPOSE: Neonatal jaundice, a frequent problem in neonatology, can be influenced by many factors. Here, we sought to clarify the role of anesthesia and to compare the effects of various anesthesiological strategies on neonatal bilirubin levels during cesarean section. METHODS: We prospectively enrolled 167 ASA I-II status uncomplicated pregnant women who delivered by cesarean section as the study group. The patients were randomized based on anesthesiological strategy: inhalation (IA), spinal (SA), total intravenous (TIVA), and epidural anesthesia (EA) groups. Neonatal total (TB) and direct bilirubin (DB) levels at the 24th hour and 5th day of life and the need for phototherapy were compared between the groups. RESULTS: Direct bilirubin levels at 24th hour of SA group and EA group were higher compared to IA group (p = 0.008). When DB levels at fifth day were compared, levels in group TIVA were significantly higher than group SA (p = 0.019). TB levels at fifth day in group TIVA were higher than SA and EA groups (p = 0.05). The percentage of newborns needing phototherapy did not differ significantly among groups, but was highest in the TIVA group (25%), followed by the IA (15%), EA (10%) and SA (7%) groups (p = 0.08). CONCLUSIONS: EA and SA at cesarean section seem to be better among the four anesthesia techniques considering neonatal hyperbilirubinemia. Our findings are consistent with the idea that anesthesia may be a risk factor for hyperbilirubinemia. Although anesthesia may not significantly increase the need for interventions such as phototherapy, it may increase the burden of time, labor and cost.

PURPOSE: Pain control after tonsillectomy is still a controversial issue. Topical approaches have the advantage of pain control with good patient acceptability. Therefore, this study was conducted to evaluate the effects of topical tramadol on postoperative pain and morbidity in children undergoing tonsillectomy. METHODS: A prospective, randomized, double-blind, controlled clinical study was designed. Forty children aged between 4 and 15 years, ASA I-II, scheduled for elective tonsillectomy and/or adenoidectomy were randomized into two groups. For patients in Group T (n = 20) swabs soaked with 2 mg/kg tramadol diluted in 10 ml saline were applied to both of their tonsillar fossa for 5 min; in the control group (n = 20) swabs soaked with 10 ml saline were applied. Postoperative pain scores, bleeding, nausea, vomiting, abdominal discomfort, constipation, pain in the throat, painful swallowing, fever, otalgia, trismus, and halitosis were recorded at the first, fifth, thirteenth, seventeenth, twenty-first, and twenty-fourth postoperative hours and the week after tonsillectomy. RESULTS: Pain scores were found to be significantly lower at the 21st hour and on postoperative day seven in the tramadol group compared with the control group (p < 0.05). Mean daily pain scores ranged from Day 1: 0.34 (±0.21) to Day 7: 0.11 (±0.08) in the tramadol group and Day 1: 0.53 (±0.14) to Day 7: 0.42 (±0.15) in the control group. There were no significant differences in morbidity between the groups (p > 0.05). CONCLUSION: Topical 5% tramadol with its local anesthetic effect seems to be an easy, safe, and comfortable approach for pain management in children undergoing tonsillectomy.

A 48-year-old female patient presented with gigantomastia. The sternal notch-nipple distance was 55 cm for the right breast and 50 cm for the left. Vertical mammaplasty based on the superior pedicle was performed. The resected tissue weighed 3400 g for the right breast and 2800 g for the left breast. The outcome was excellent with respect to symmetry, shape, size, residual scars, and sensitivity of the nipple-areola complex. Longer pedicles or larger resections were not found in the literature on vertical mammaplasty applications. In our opinion, by using the vertical mammaplasty technique in gigantomastia it is possible to achieve a well-projecting shape and preserve NAC sensitivity.

BACKGROUND: In this study, we compared the use of preincisional lidocaine 2% with epinephrine (LA) and levobupivacaine 0.25% plain (LB) for postoperative analgesia and vasoconstriction in patients undergoing nasal surgery. METHODS: Sixty patients were randomly assigned to receive preincisional local infiltration under general anesthesia. Group LB received levobupivacaine 0.25%, and group LA received epinephrine plus lidocaine 2% (add volume injected). Intraoperative hemodynamic changes, pre- and postoperative hemoglobin and hematocrit values were recorded. Visual analog scale values 30 min and 1, 2, 8, 12, and 24 h postoperatively and the need for rescue analgesic treatment in the first 24 h of all patients was recorded. RESULTS: At 30 min and 1, 2, 8, and 12 h postoperatively, visual analog scale values were lower in group LB than in group LA (P < 0.0001, P = 0.002, P = 0.023, P < 0.0001, and P = 0.011, respectively). The analgesic requirement was significantly lower in group LB when compared with that in group LA (P = 0.038). Group LB had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.014 and 0.025). Group LA had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.031 and 0.024). CONCLUSIONS: We conclude that postoperative analgesia in nasal surgery with local infiltration of levobupivacaine was significantly more potent and longer lasting than that achieved by lidocaine plus epinephrine.

OBJECTIVES: The aim of this study was to compare a transversus abdominis plane (TAP) block guided with ultrasound (USG) and local anesthetic infiltration (LAI) in terms of the intraoperative and postoperative analgesia efficiency, intraoperative opioid need, and side effects in cases of laparoscopic cholecystectomy. METHODS: A total of 75 patients classified as American Society of Anesthesiologists class I or II were included in this randomized, controlled, prospective study and divided into 3 groups. 20 mL of levobupivacaine 0.5% was applied around the trocar entrance site before the operation to group L (n=25), and 30 mL 0.25% levobupivacaine was applied with a USG-guided TAP block to group T (n=25). No TAP block or LAI was applied to the control group (n=25), group K. In the first 24 hours after surgery, an infusion of tramadol was administered with a controlled analgesia device. The intraoperative fentanyl use was recorded, and a visual analogue scale was administered to assess pain while resting (VASrest) and upon coughing (VAScough) at 1, 2, 4, 8, 12, 16, and 24 hours postoperative. An evaluation of shoulder pain and the consumption of analgesia in 24 hours were also recorded. RESULTS: The VASrest and VAScough values, the dose of fentanyl used intraoperatively, and the total analgesia dose administered in 24 hours were compared between groups and there was no statistically significant difference detected (p>0.05). In group T, the vomiting rate 1 and 2 hours postoperative (20% and 12%, respectively) was significantly lower than in group K (64% and 44%, respectively). CONCLUSION: The efficiency of the analgesia provided after a laparoscopic cholecystectomy with a bilateral TAP block guided with USG and LAI was determined to be similar.

OBJECTIVE: To evaluate the effects of desflurane on middle ear pressure. STUDY DESIGN: A prospective clinical study. METHODS: In this study, 38 ears of 19 male children that were scheduled for circumcision were included. Baseline tympanometry reading was performed on each ear just before anesthesia. After induction anesthesia with propofol a laryngeal mask was applied and desflurane administration was started. The next tympanometry reading was taken at 5th, 10th and 15th minute after administration and at the 10th minute after the cessation of desflurane. Data were analysed using Wilcoxon test. RESULTS: Mean MEP values before anesthesia in 38 ears of 19 boys were -10.32+/-33.14. After starting the administration of desflurane 5th minute mean value was 71.15+/-60.42, at the 10 th minute 111.56+/-59.03 and at the 15th minute it increased to 120.50+/-54.14, and these measurements were significantly higher than the starting value (p<0.001). After cessation of desflurane mean MEP value dropped to 57.56+/-79.06, but compared with the starting value this was also significantly higher (p<0.001). CONCLUSION: Desflurane may increase the middle ear pressure and it may be unsuitable for certain middle ear surgeries.

BACKGROUND AND OBJECTIVES: Desflurane and sevoflurane are frequently used for maintenance of anesthesia and studies have shown that these anesthetics cause a variety of changes to the oxidative stress and antioxidative defense mechanisms. This study aims to compare the effects of sevoflurane, desflurane and propofol infusion anesthesia on the oxidant and antioxidant systems of patients undergoing laparoscopic cholecystectomy. METHODS: 45 patients between 18 and 50 years with planned laparoscopic cholecystectomy under general anesthetic were included in the study. Patients were divided into three groups on the way to surgery: propofol (group P, n=15), sevoflurane (group S, n=15) and desflurane (group D, n=15). All groups were given hypnotic 2mg/kg propofol IV, 1mcg/kg fentanyl IV and 0.1mg/kg vecuronium IV for induction. For maintenance of anesthesia group S were ventilated with 2% sevoflurane, group D cases were given 6% desflurane and group P were given propofol infusions of 12mg/kg/h for the first 10minutes, 9mg/kg/h for the second 10minutes and 6mg/kg/h after that. Before induction and after the operation venous blood samples were taken to evaluate the levels of glutation peroxidase, total oxidants and antioxidants. RESULTS AND CONCLUSIONS: The 45 patients included in the study were 22 male and 23 female patients. The demographic characteristics of the groups were similar. In the postoperative period we observed that while sevoflurane and propofol increased antioxidants by a statistically significant level, desflurane increased the total oxidants level by a significant amount compared to levels before the operation.
RESUMO
AIM: Corrosive esophageal burns are still an important problem. The aim of this study was to evaluate the effect of kefir in an experimental corrosive esophagitis model. MATERIAL AND METHOD: Twenty-four male wistar albino rats were used in this experimental study. The rats were randomized into three groups according to the procedure and treatment type (each group has eight rats). Group I: (Control group), Group II: (Induction of corrosive esophagitis with 5 % NaOH without any treatment) and Group III: (Corrosive esophagitis treated with kefir). The rats were sacrificed on the first and seventh days. Mediastinum and abdominal cavity of rats were explorated. Approximately 1.5 cm of esophagus was removed for histopathological examination. Inflammation, injury in the muscularis mucosa and collagen deposition were evaluated. RESULTS: Histopathological results on the first day after caustic injury; inflammation was detected in three rats in Group II and there were no inflammation in rats in Group III. This difference was statistically significant (p<0.05). Injury in muscularis mucosa was detected in three rats in Group II and in one rat in Group III. Histopathological results on the seventh days after caustic injury; Inflammation was positive in four rats in Group II and three rats in Group III. Injury in muscularis mucosa was equal in two groups (three rats each). Collagen deposition with high grade (Grade 2) was detected in two rats in Group II and in four rats in Group III (p<0.05). CONCLUSION: Kefir has anti-inflammatory effect specially in early phase of caustic injury. It has also some beneficial effect in wound healing.

BACKGROUND: Carbon dioxide (CO2) pneumoperitoneum facilitates the visualization of abdominal organs during laparoscopic surgery. However, the associated increase in intra-abdominal pressure causes oxidative stress, which contributes to tissue injury. OBJECTIVE: We investigated the ability of the antioxidant and anti-inflammatory drug Erdosteine to prevent CO2 pneumoperitoneum-induced oxidative stress and inflammatory reactions in a rat model. METHODS: Fourteen female adult Wistar albino rats were divided into a control group (Group A, n = 7) and an Erdosteine group (Group B, n = 7). Group A received 0.5 cc/day 0.9% NaCl, and Group B received 10 mg/kg/day Erdosteine was administered by gavage, and maintained for 7 days prior to the operation. During the surgical procedure, the rats were exposed to CO2 pneumoperitoneum with an intra-abdominal pressure of 15 mmHg for 30 min. The peritoneal gas was then desufflated. The rats were sacrificed following 3 h of insufflation. Their lungs were removed, histologically evaluated, and scored for intra-alveolar hemorrhage, alveolar edema, congestion, and leukocyte infiltration. The results were statistically analyzed. A value of P < 0.05 was considered statistically significant. RESULTS: Significant differences were detected in intra-alveolar hemorrhage (P < 0.05), congestion (P < 0.001), and leukocyte infiltration (P < 0.001) in Group A compared with Group B. However, the differences in alveolar edema were not statistically significant (P = 0.698). CONCLUSIONS: CO2 pneumoperitoneum results in oxidative injury to lung tissue, and administration of Erdosteine reduces the severity of pathological changes. Therefore, Erdosteine may be a useful preventive and therapeutic agent for CO2 pneumoperitoneum-induced oxidative stress in laparoscopic surgery.

BACKGROUND: Accidents caused by motorized vehicle in the agricultural sector are frequently observed. In Turkey; accidents arising from motorized vehicles, named Pat-Pat, which are used by farmers in the Western Black Sea region is not unusual. METHODS: One hundred five patients who were brought into the Emergency Department of Duzce University, Medical Faculty Hospital between September 2009 and August 2010 due to Pat-Pat related accidents were evaluated. RESULTS: The cases consisted of 73 (69.5%) males and 32 (30.5%) females, ranging from 2 to 73 years of age. In the 10-39 age group, a total of 63 (60.0%) cases were determined. The months when the greatest rate of cases applied to the hospital consisted of July, August, September and the season is summer. The cases were exposed to trauma in roads in 54 (51.4%), and 51 (48.6%) occurred in agricultural area without roads. Eighty seven (82.9%) cases were injured due to the overturning of vehicle. The patients were brought to the hospital using a private vehicle in 54 (51.4%) of the cases and in 51 (48.6%) cases, 112 ambulance system was used. The cases were determined to apply to the hospital most frequently between 6 pm-12 am. The injuries frequently consisted of head-neck and spine traumas, thorax traumas and upper extremity traumas. In 55 (52.4%) cases, open wound-laceration was determined. Seventy five (71.4%) cases were treated in the Emergency Department, and 28 (26.7%) were hospitalized. Three (2.9%) cases were deceased. CONCLUSIONS: Serious injuries can occur in Pat-Pat related accidents, and careful systematic physical examination should be conducted. In order to prevent these accidents, education of farm operators and engineering studies on the mechanics and safety of these vehicles should be taken and legal regulations should be created.

We report a case of acute respiratory insufficiency due to peripartum cardiomyopathy after Caesarean section in a term pregnancy with twins. The patient was a 30-year-old woman with a spontaneous twin pregnancy at 32 weeks of gestation who was admitted to our obstetrics department with preterm premature rupture of membranes. After 48 hours, the tocolysis was stopped and an uneventful Caesarean was performed under general anesthesia. As the patient was waking up, her SPO2 decreased to 32%, and she became cyanotic and tachypneic. Auscultation revealed rales in her lower lung lobes bilaterally. Her oxygen saturation did not increase in the hours that followed, and her cyanosis persisted, so we decided to admit her to the Intensive Care Unit. She was mechanically ventilated. Her chest X-ray showed an enlarged cardiac silhouette and pulmonary infiltrates in the lower lobes. On the second postoperative day, transthoracic echocardiography was performed and revealed an EF of 45%, mild left ventricular systolic dysfunction and moderate mitral valve failure. Lisinopryl and furosemide were started. On postoperative day four, her symptoms and radiological signs had resolved. She was weaned from mechanical ventilation and discharged from the obstetric ward on postoperative day seven.
RESUMO
PURPOSE: Extracorporeal shockwave lithotripsy (SWL) is the mainstay treatment modality for upper urinary tract stones. However, it is a relatively painful procedure and so an efficient analgesia is required for better clinical success. The ideal method of anesthesia has not been standardized. The objective of this randomized study, for the first time in the literature, was to compare the efficacy of three common analgesics, each belonging to a different group, in pain control during SWL. PATIENTS AND METHODS: In this randomized controlled study, 90 patients with upper urinary tract stones undergoing SWL were randomly divided into three groups. Group I (n = 30) received 1 g of paracetamol, group II (n = 30) received 8 mg of lornoxicam, and group III (n = 30) had 1 mg/kg of tramadol. No premedication was applied in all groups. Pain scores by visual analog scale (VAS), blood pressure, heart rate, respiratory rate, and peripheral oxygen saturation were noted before procedure and at 1 minute and every 5 minutes during the SWL. Supplementary analgesic consumption was recorded. Moreover, all adverse effects and both patient and urologist satisfaction were documented. RESULTS: Demographic parameters of the three groups were similar. All monitored parameters were also not different among the groups. The mean VAS scores at all measured times during SWL were below 4 except for two occasions, indicating a relatively efficient overall pain control provided by these three medications. Moreover, the mean VAS scores were similar among these three groups at all measured times during SWL except for those at 5 and 20 minutes at which groups III and II showed lesser pain control, respectively. No difference was observed in the amount of supplementary analgesia, which was required at higher voltages in a majority of patients. There was no significant difference in side effects. CONCLUSION: This study suggests that paracetamol, lornoxicam, and tramadol can be safely and efficiently preferred in pain control during SWL.

BACKGROUND AND OBJECTIVES: Desflurane and sevoflurane are frequently used for maintenance of anesthesia and studies have shown that these anesthetics cause a variety of changes to the oxidative stress and antioxidative defense mechanisms. This study aims to compare the effects of sevoflurane, desflurane and propofol infusion anesthesia on the oxidant and antioxidant systems of patients undergoing laparoscopic cholecystectomy. METHODS: 45 patients between 18 and 50 years with planned laparoscopic cholecystectomy under general anesthetic were included in the study. Patients were divided into three groups on the way to surgery: propofol (group P n: 15), sevoflurane (group S n: 15) and desflurane (group D n: 15). All groups were given hypnotic 2 mg/kg propofol IV, 1 mcg/kg fentanyl IV and 0.1 mg/kg vecuronium IV for induction. For maintenance of anesthesia group S were ventilated with 2% sevoflurane, group D cases were given 6% desflurane and group P were given propofol infusions of 12 mg/kg/h for the first 10 min, 9 mg/kg/h for the second 10 min and 6 mg/kg/h after that. Before induction and after the operation venous blood samples were taken to evaluate the levels of glutation peroxidase, total oxidants and antioxidants. RESULTS AND CONCLUSIONS: The 45 patients included in the study were 22 male and 23 female patients. The demographic characteristics of the groups were similar. In the postoperative period we observed that while sevoflurane and propofol increased antioxidants by a statistically significant level, desflurane increased the total oxidants level by a significant amount compared to levels before the operation. .
JUSTIFICATIVA E OBJETIVOS: Desflurano e sevoflurano são usados com frequência para a manutenção da anestesia e estudos mostraram que esses anestésicos causam alterações variadas nos mecanismos de defesa antioxidante contra o estresse oxidativo. Este estudo teve como objetivo comparar os efeitos de anestesias com perfusão de sevoflurano, desflurano e propofol sobre os sistemas oxidante/antioxidante de pacientes submetidos à colecistectomia laparoscópica. MÉTODOS: Foram incluídos no estudo 45 pacientes entre 18 e 50 anos, agendados para colecistectomia laparoscópica sob anestesia geral. Os pacientes foram divididos em três grupos para receberem propofol (Grupo P, n = 15), sevoflurano (Grupo S, n = 15) e desflurano (Grupo D, n = 15). Todos os grupos receberam 2 mg/kg de propofol IV, 1 mcg/kg de fentanil IV e 0,1 mg/kg de vecurônio IV para indução. Para manutenção da anestesia, o Grupo S recebeu ventilação com sevoflurano a 2%, o Grupo D recebeu desflurano a 6% e o Grupo P recebeu propofol em perfusões de 12 mg/kg/h nos primeiros 10 minutos, 9 mg/kg/h nos 10 minutos seguintes e 6 mg/kg/h subsequentemente. Antes da indução e depois da cirurgia, amostras de sangue venoso foram colhidas para avaliar os níveis de glutationa peroxidase e o total de oxidantes e antioxidantes. RESULTADOS E CONCLUSÕES: Dos 45 pacientes incluídos no estudo, 22 eram do sexo masculino e 23 do feminino. As características demográficas dos grupos eram semelhantes. No período pós-operatório, observamos que enquanto sevoflurano e propofol aumentaram os antioxidantes a um nível de significância estatística, desflurano aumentou o nível total de oxidantes em quantidade significativa, em comparação com os níveis pré-operação. .

OBJECTIVE: To reduce the post-tonsillectomy morbidity by swab soaked with 5 ml levobupivacaine hydroclorur (25 mg/10 ml). STUDY DESIGN: A double-blind prospective randomized controlled clinical study. METHODS: In this randomized double-blind study in group I (30 children, mean age 7.5+/-2.6) we tightly packed swab soaked with 5 ml levobupivacaine hydroclorur (25mg/10 ml) and in group II (21 children, mean age 7.9+/-3.7) we used 5 ml saline swabs into each of the two tonsillar fossae after tonsillectomy for 5 min. We used McGrath's face scale to compare the two groups in respect of pain control. RESULTS: There was statistically significant pain relieving effect in the levobupivacaine group in the first 24h (p<0.05). But after 24h pain relieving effect of levobupivacaine was not significant (p>0.05). We did not see any serious complications for both groups. Postoperative morbidity mean results (nausea, vomiting, fever, bleeding, halitosis and ear pain) were not statistically different between the two groups (p>0.05). CONCLUSION: Topical levobupivacaine seems to be a safe and easy medication for postoperative pain control in pediatric tonsillectomy patients.

PURPOSE: Intrathecal morphine is administered to provide profound and prolonged analgesia, and to treat acute postoperative pain. We compared the effectiveness of hyperbaric bupivacaine alone and in combination with morphine for unilateral spinal anesthesia in patients undergoing knee arthroscopy. METHODS: Sixty patients were randomly allocated to two groups to receive either 1.2 ml (6 mg) of 0.5% hyperbaric bupivacaine (group B; n = 30) or 1.2 ml of 0.5% hyperbaric bupivacaine containing 0.16 mg of morphine (group BM; n = 30). Spinal block was assessed by pinprick and a modified Bromage scale and compared between the operated and nonoperated sides. Visual analog scale (VAS) values, duration of analgesia, and total analgesic requirement of patients were recorded. RESULTS: Patients in group BM had significantly lower VAS values on movement at 30 min and at 2, 4, 6, and 12 h postoperatively (P < 0.05 and P < 0.001, P < 0.001, P < 0.001, and P < 0.05, respectively). The total analgesic requirement in the first 24 h after surgery was significantly higher in group B (P < 0.001). Patients in group BM had a significantly longer duration of analgesia in the first 24 h postoperatively (P < 0.001). Motor blockade of the operated limb in group BM was similar to that in group B (P > 0.05), and motor blockade of the nonoperated limb in group BM was also similar to that in group B (P > 0.05). CONCLUSION: We conclude that unilateral spinal anesthesia with hyperbaric bupivacaine plus 0.16 mg morphine is preferable to hyperbaric bupivacaine alone with respect to analgesic requirement, duration of analgesia, and VAS values.
