Comparison of sugammadex and neostigmine-atropine on intraocular pressure and postoperative effects.

During surgery, changes in intraocular pressure (IOP) can be observed resulting from several factors, such as airway manipulations and drugs used. We aimed to investigate the effects of sugammadex and neostigmine on IOP, hemodynamic parameters, and complications after extubation. Our study comprised 60 patients, aged 18-65 years, with a risk status of the American Society of Anesthesiologists I-II who underwent arthroscopic surgery under general anesthesia. The patients were randomly assigned into two groups. At the end of the surgery, the neuromuscular block was reversed using neostigmine (50 µg/kg) plus atropine (15 µg/kg) in Group 1, and sugammadex (4 mg/kg) in Group 2. Neuromuscular blockade was monitored using acceleromyography and a train-of-four mode of stimulation. IOP was measured before induction and at 30 seconds, 2 minutes, and 10 minutes after extubation. A Tono-Pen XL applanation tonometer was used to measure IOP. This showed that elevation in IOP of patients reversed using sugammadex was similar to that recorded in patients reversed using neostigmine-atropine. When heart rate was compared, there was a significant difference between basal values and those obtained at 30 seconds and 10 minutes after extubation in the neostigmine-atropine group. Extubation time (time from withdrawal of anesthetic gas to extubation) was significantly shorter in the sugammadex group (p = 0.003) than in the neostigmine-atropine group. The postextubation IOP values of the sugammadex group were similar to the neostigmine-atropine group. Extubation time (time from withdrawal of anesthetic gas to extubation) was significantly shorter in the sugammadex group (p = 0.003) than in the neostigmine-atropine group.

Cost-Conscious of Anesthesia Physicians: An awareness survey.

OBJECTIVE: Increasing competitive pressure and health performance system in the hospitals result in pressure to reduce the resources allocated. The aim of this study was to evaluate the anesthesiology and intensive care physicians awareness of the cost of the materials used and to determine the factors that influence it. METHODS: This survey was conducted between September 2012 and September 2013 after the approval of the local ethics committee. Overall 149 anesthetists were included in the study. Participants were asked to estimate the cost of 30 products used by anesthesiology and intensive care units. RESULTS: One hundred forty nine doctors, 45% female and 55% male, participated in this study. Of the total 30 questions the averages of cost estimations were 5.8% accurate estimation, 35.13% underestimation and 59.16% overestimation. When the participants were divided into the different groups of institution, duration of working in this profession and sex, there were no statistically significant differences regarding accurate estimation. However, there was statistically significant difference in underestimation. In underestimation, there was no significant difference between 16-20 year group and >20 year group but these two groups have more price overestimation than the other groups (p=0.031). Furthermore, when all the participants were evaluated there were no significant difference between age-accurate cost estimation and profession time-accurate cost estimation. CONCLUSION: Anesthesiology and intensive care physicians in this survey have an insufficient awareness of the cost of the drugs and materials that they use. The institution and experience are not effective factors for accurate estimate. Programs for improving the health workers knowledge creating awareness of cost should be planned in order to use the resources more efficiently and cost effectively.

[Assessment of the perioperative period in civilians injured in the Syrian Civil War]. / Avaliação do período perioperatório em civis feridos na Guerra Civil Síria.

BACKGROUND: Wars and its challenges have historically afflicted humanity. In Syria, severe injuries occurred due to firearms and explosives used in the war between government forces and civilians for a period of over 2 years. MATERIALS AND METHODS: The study included 364 cases, who were admitted to Mustafa Kemal University Hospital, Medicine School (Hatay, Turkey), and underwent surgery. Survivors and non-survivors were compared regarding injury site, injury type and number of transfusions given. The mortality rate found in this study was also compared to those reported in other civil wars. RESULTS: The mean age was 29 (3-68) years. Major sites of injury included extremities (56.0%), head (20.1%), abdomen (16.2%), vascular structures (4.4%) and thorax (3.3%). Injury types included firearm injury (64.4%), blast injury (34.4%) and miscellaneous injuries (1.2%). Survival rate was 89.6% while mortality rate was 10.4%. A significant difference was observed between mortality rates in this study and those reported for the Bosnia and Lebanon civil wars; and the difference became extremely prominent when compared to mortality rates reported for Vietnam and Afghanistan civil wars. CONCLUSION: Among injuries related to war, the highest rate of mortality was observed in head-neck, abdomen and vascular injuries. We believe that the higher mortality rate in the Syrian Civil War, compared to the Bosnia, Vietnam, Lebanon and Afghanistan wars, is due to seeing civilians as a direct target during war.

JUSTIFICATIVA: Historicamente, as guerras e seus desafios afligem a humanidade. Na Síria, lesões graves ocorreram devido às armas de fogo e explosivos usados na guerra entre as forças governamentais e civis durante um período de mais de dois anos. MATERIAIS E MÉTODOS: O estudo incluiu 364 pacientes, admitidos no Hospital da Universidade Mustafa Kemal da Faculdade de Medicina (Hatay, Turquia) e submetidos à cirurgia. Os sobreviventes e não sobreviventes foram comparados quanto ao local e tipo da lesão e número de transfusões administradas. A taxa de mortalidade encontrada neste estudo também foi comparada àquelas relatadas em outras guerras civis. RESULTADOS: A média de idade foi de 29 (3-68) anos. Os principais locais de lesão incluíram extremidades (56,0%), cabeça (20,1%), abdome (16,2%), estruturas vasculares (4,4%) e tórax (3,3%). Os tipos de lesões incluíram ferimento de arma de fogo (64,4%), lesão causada por explosão (34,4%) e ferimentos diversos (1,2%). A taxa de sobrevivência foi de 89,6%, enquanto a taxa de mortalidade foi de 10,4%. Observou-se uma diferença significativa entre as taxas de mortalidade neste estudo e aquelas relatadas para as guerras civis da Bósnia e Líbano; e a diferença ficou extremamente significativa quando comparada com as taxas de mortalidade relatadas para as guerras civis do Vietnã e do Afeganistão. CONCLUSÃO: Dentre as lesões relacionadas à guerra, a maior taxa de mortalidade foi observada em lesões de cabeça-pescoço, abdome e vasculares. Acreditamos que a maior taxa de mortalidade na Guerra Civil da Síria, em comparação com as guerras da Bósnia, Vietnã, Líbano Afeganistão, se deva ao fato de os civis terem sido vistos como alvo direto durante a guerra.

Effectiveness of sub-Tenon's block in pediatric strabismus surgery / Eficácia do bloqueio subtenoniano em cirurgia de estrabismo pediátrico

ABSTRACTBACKGROUND AND OBJECTIVES: Strabismus surgery is a frequently performed pediatric ocular procedure. A frequently occurring major problem in patients receiving this treatment involves the oculocardiac reflex. This reflex is associated with an increased incidence of postoperative nausea, vomiting, and pain. The aim of this study was to investigate the effects of a sub-Tenon's block on the oculocardiac reflex, pain, and postoperative nausea and vomiting.METHODS: 40 patients aged 5-16 years with American Society of Anesthesiologists status I-II undergoing elective strabismus surgery were included in this study. Patients included were randomly assigned into two groups by using a sealed envelope method. In group 1 (n = 20), patients did not receive sub-Tenon's anesthesia. In group 2 (n = 20), following intubation, sub-Tenon's anesthesia was performed with the eye undergoing surgery. Atropine use, pain scores, oculocardiac reflex, and postoperative nausea and vomiting incidences were compared between groups.RESULTS: There were no significant differences between groups with regard to oculocardiac reflex and atropine use (p > 0.05). Pain scores 30 min post-surgery were significantly lower in group 2 than in group 1 (p < 0.05). Additional analgesic needed during the postoperative period was significantly lower in group 2 compared to group 1 (p < 0.05).CONCLUSIONS: In conclusion, we think that a sub-Tenon's block, combined with general anesthesia, is not effective and reliable in decreasing oculocardiac reflex and postoperative nausea and vomiting. However, this method is safe for reducing postoperative pain and decreasing additional analgesia required in pediatric strabismus surgery.

RESUMOJUSTIFICATIVA E OBJETIVO: A cirurgia de estrabismo é um procedimento oftalmológico comum em pediatria. Um grande problema que ocorre com frequência em pacientes submetidos a esse tratamento envolve o reflexo oculocardíaco. Esse reflexo está associado ao aumento da incidência de náusea, vômito e dor. O objetivo deste estudo foi investigar os efeitos do bloqueio subtenoniano sobre o reflexo oculocardíaco, a dor, a náusea e o vômito no período pós-operatório.MÉTODOS: Foram incluídos no estudo 40 pacientes entre 5-16 anos, estado físico ASA I-II, submetidos à cirurgia eletiva de estrabismo. Foram randomicamente alocados em dois grupos, com o método de envelope lacrado. No Grupo 1 (n = 20),pacientes não receberam bloqueio subtenoniano. No Grupo 2 (n = 20), após a intubação, o bloqueio subtenoniano foi feito no olho submetido à cirurgia. Uso de atropina, escores de dor, reflexo oculocardíaco e incidência de náusea e vômito foram comparados.RESULTADOS: Não houve diferença significativa entre os grupos em relação ao reflexo oculocardíaco e ao uso de atropina (p > 0,05). Os escores de dor em 30 minutos de pós-operatório foram significativamente menores no Grupo 2 do que no Grupo 1 (p < 0,05). A necessidade de analgésico adicional durante o período pós-operatório foi significativamente menor no Grupo 2 do que no Grupo 1 (p < 0,05).CONCLUSÕES: O bloqueio subtenoniano, em combinação com anestesia geral, não é eficaz e confiável para diminuir o reflexo oculocardíaco, bem como náusea e vômito pós-operatórios (NVPO). Porém, esse método é seguro para diminuir a dor no período pós-operatório e reduzir a analgesia adicional necessária em cirurgia de estrabismo pediátrico.

Intraoperative Ephedrine Allergy in a Patient Who Received Chemotherapy and Perioperative Hypersensitivity Reactions.

Anaesthesia represents a specific set-up in respect to pharmacology, and during this time, early hypersensitivity reactions or anaphylaxis may occur in patients who are exposed to a great number of foreign substances. Intravenous ephedrine (5 mg) was applied to a 37-year-old patient due to the development of intraoperative hypotension in a total abdominal hysterectomy operation. After application, hyperaemia was seen in the track of the intravenous catheter of that extremity. Approximately 15 minutes later, urticarial plaques were observed extensively in the abdomen and in both extremities. Methylprednisolone (100 mg+100 mg) and pheniramine (45.5 mg) were given with an increasing infusion rate of intravenous crystalloid. The patient was extubated without any problem and removed to the recovery unit for observation. After the total disappearance of lesions at postoperative 60 minutes and because of the stability of vital signs, the patient was removed to the service. In the follow-up of surgery, no complication developed, and the patient was discharged on postoperative day 2.

The effects of remifentanil and esmolol on increase in intraocular pressure due to laryngoscopy and tracheal intubation: a double-blind, randomized clinical trial.

PURPOSE: This study aimed to compare the effects of remifentanil and esmolol on the elevation of intraocular pressure (IOP) and hemodynamic response. METHODS: After approval of the institutional Ethics Committee and obtaining informed consent, 60 adult patients with American Society of Anesthesiologists I-II status undergoing elective, nonophthalmic surgery were included in the study. Exclusion criteria were preexisting eye disease, neuromuscular disease, esophageal reflux, hiatus hernia, allergy to any of the study drugs, and the use of ß-blockers, diuretics, or other antihypertensive agents. The patients were randomized into 2 groups by using the sealed-envelope method, as follows: group E (esmolol) and group R (remifentanil). A single intravenous dose of esmolol (0.5 mg/kg) or remifentanil (1 µg/kg) just before induction agents were given to patients in groups E and R, respectively. IOP, heart rate (HR), and mean arterial pressure (MAP) values were recorded before intubation and at 1, 3, 5, and 10 minutes after intubation. RESULTS: The IOP decrease in group R was statistically significant compared with group E (P<0.01). HR values at 10 minutes after intubation were significantly decreased in group E compared with group R (P<0.05). There was no significant difference in MAP values between the groups. CONCLUSIONS: It was concluded that remifentanil is more effective than esmolol in preventing IOP elevation related to laryngoscopy and tracheal intubation, while there is no significant difference between the 2 agents in terms of HR and MAP.

Effect of carboxyhemoglobin on postoperative complications and pain in pediatric tonsillectomy patients.

BACKGROUND: Carbon monoxide (CO) is a product of burning solid fuel in stoves and smoking. Exposure to CO may provoke postoperative complications. Furthermore, there appears to be an association between COHb concentrations and pain. We thus tested the primary hypothesis that children with high preoperative carboxyhemoglobin (COHb) concentrations have more postoperative complications and pain after tonsillectomies, and secondarily that high-COHb concentrations are associated with more pain and analgesic use. METHODS: 100 children scheduled for elective tonsillectomy were divided into low and high carbon monoxide (CO) exposure groups: COHb ≤3 or ≥4 g·dl(-1) . We considered a composite of complications during the 7 days after surgery which included bronchospasm, laryngospasm, persistent coughing, desaturation, re-intubation, hypotension, postoperative bleeding, and reoperation. Pain was evaluated with Wong-Baker Faces pain scales, and supplemental tramadol use recorded for four postoperative hours. RESULTS: There were 36 patients in the low-exposure group COHb [1.8 ± 1.2 g·dl(-1) ], and 64 patients were in the high-exposure group [6.4 ± 2.1 g·dl(-1) ]. Indoor coal-burning stoves were reported more often by families of the high- than low-COHb children (89% vs 72%, P < 0.001). Second-hand cigarette smoke exposure was reported by 54% of the families with children with high COHb, but only by 24% of the families of children with low COHb. Composite complications were more common in patients with high COHb [47% vs 14%, P = 0.0001, OR:7.4 (95% Cl, lower = 2.5-upper = 21.7)], with most occurring in the postanesthesia care unit. Pain scores in postanesthesia care unit and one hour after surgery were statistically significantly lower in the low-exposure group [respectively, P = 0.020 (95%CI, lower = -1.21-upper = -0.80), P = 0.026 (95% CI, lower = -0.03-upper = 0.70)], and tramadol use increased at 4 h (3.5 (interquartile range: 0-8) vs 6 (5-9) mg, P = 0.012) and 24 h (3.5 (0-8) vs 6 (5-9) mg, P = 0.008). CONCLUSION: High preoperative COHb concentrations are associated with increased postoperative complications and pain.

Efficacy of resuscitation with Intralipid in a levobupivacaine-induced cardiac arrest model.

AIM: Cardiac toxicity due to the administration of local anesthetics may be fatal. In this study, we evaluated the efficacy of a 20% lipid solution combined with epinephrine in a levobupivacaine-induced cardiac arrest model. MATERIALS AND METHODS: A total of 14 New Zealand rabbits were sedated and mechanically ventilated. Asystole was induced with intravenous levobupivacaine injection. The rabbits were randomized into groups receiving the same volume of either 0.9% saline (CR group) or a 20% lipid solution (LE group) along with a 100 µg/kg epinephrine bolus, which were administered immediately upon asystole. Standard advanced cardiac life support protocols were performed. RESULTS: Four subjects in the LE group as well as 3 subjects in the CR group had a spontaneous recovery (P = 0.592). In the 20th minute after arrest, 3 subjects in the LE group had maintained spontaneous circulation, while there was only 1 subject from the CR group with the same outcome. CONCLUSION: We found that adding a lipid solution to epinephrine for the resuscitation of rabbits that underwent levobupivacaine- induced cardiac arrest increased recovery rates of circulation and therefore the likelihood of survival. Further studies are needed to develop clinical therapies for the systemic toxicity of local anesthetics.

The development of ventricular fibrillation due to etomidate for anesthetic induction: a very rare side effect, case report / Desenvolvimento de fibrilação ventricular por causa de etomidato para indução anestésica: um efeito colateral muito raro, relato de caso / Desarrollo de fibrilación ventricular debido al etomidato para la inducción anestésica: un efecto colateral muy raro, relato de caso

Background and objectives: Ventricular fibrillation occurring in a patient can result in unexpected complications. Here, our aim is to present a case of ventricular fibrillation occurring immediately after anesthesia induction with etomidate administration. Case report: A fifty-six-year-old female patient with a pre-diagnosis of gallstones was admitted to the operating room for laparoscopic cholecystectomy. The induction was performed by etomidate with a bolus dose of 0.3 mg/kg. Severe and fast adduction appeared in the patient's arms immediately after induction. A tachycardia with wide QRS and ventricular rate 188 beat/min was detected on the monitor. The rhythm turned to VF during the preparation of cardioversion. Immediately we performed defibrillation to the patient. Sinus rhythm was obtained. It was decided to postpone the operation due to the patient's unstable condition. Conclusion: In addition to other known side effects of etomidate, very rarely, ventricular tachycardia and fibrillation can be also seen. To the best of our knowledge, this is the first case regarding etomidate causing VF in the literature. .

Justificativa e objetivos: A ocorrência de fibrilação ventricular em um paciente pode resultar em complicações inesperadas. Nosso objetivo é apresentar um caso de fibrilação ventricular que ocorreu após a indução anestésica com administração de etomidato. Relato de caso: Paciente do sexo feminino, 56 anos, com pré-diagnóstico de cálculos biliares, foi admitida na sala de cirurgia para colecistectomia laparoscópica. A anestesia foi induzida com a administração de etomidato com uma dose em bolus de 0,3 mg/kg. A paciente apresentou uma grave e rápida adução dos braços logo após a indução. Taquicardia com QRS largo e frequência ventricular de 188 bpm foram detectadas no monitor. O ritmo converteu-se em fibrilação ventricular (FV) durante a preparação para a cardioversão. A paciente foi imediatamente submetida a desfibrilação. O ritmo sinusal foi obtido. Decidimos adiar a cirurgia por causa da condição de instabilidade da paciente. Conclusão: Além dos efeitos secundários conhecidos de etomidato, taquicardia ventricular e fibrilação, embora muito raramente, também podem ser observadas. Até onde sabemos, esse é o primeiro caso na literatura de FV causado por etomidato. .

Hasta donde sabemos, este es el primer caso de fibrilación ventricular causado por etomidato en la literatura. .

The impact of different antiepileptic drugs on the sedation of children during magnetic resonance imaging / Impacto de diferentes medicamentos antiepilépticos na sedação de crianças durante a ressonância magnética / Impacto de diferentes medicamentos antiepilépticos en la sedación de niños durante la resonancia magnética

Background and objectives: The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance imaging in epileptic children receiving antiepileptic drugs that cause either enzyme induction or inhibition. Methods: In American Society of Anesthesiology I–II, 120 children aged 3–10 years were included. Group 1: children using antiepileptic drugs that cause cytochrome P450 enzyme induction; Group 2: those using antiepileptic drugs that cause inhibition; and Group 3: those that did not use antiepileptic drugs. Sedation was induced with the use of 0.05 mg kg−1 midazolam and 1 mg kg−1 propofol. An additional 0.05 mg kg−1 of midazolam and rescue propofol (0.5 mg kg−1) were administered and repeated to maintain sedation. The duration of sedation and the additional sedation needed were compared. Results: The duration of the initial dose was significantly shorter in Group I compared with groups II and III (p = 0.001, p = 0.003, respectively). It was significantly longer in Group II compared with groups I and III (p = 0.001, p = 0.029, respectively). The additional midazolam needed for adequate sedation was increased in Group I when compared with groups II and III (p = 0.010, p = 0.001, respectively). In addition, the rescue propofol dose was significantly higher only in Group I when compared with Group III (p = 0.002). Conclusion: In epileptic children, the response variability to the initial sedative agents during the magnetic resonance imaging procedure resulting from the inhibition or induction of the cytochrome P450 isoenzymes by the antiepileptic drugs mandated the titration of anesthetic agents. .

Justificativa e objetivos: A indução e a inibição das isoenzimas do citocromo P450 pelos medicamentos antiepilépticos levam a alterações na depuração de medicamentos anestésicos eliminados pelo metabolismo hepático. Investigamos a duração da sedação e a necessidade adicional de anestésicos durante a ressonância magnética em crianças epilépticas que receberam antiepilépticos que causam a indução ou a inibição de enzimas. Métodos: Foram incluídas no estudo 120 crianças, estado físico ASA I-II, entre 3-10 anos. Grupo 1: em uso de antiepilépticos que causam a indução de enzimas do citocromo P450; Grupo 2: em uso de antiepilépticos que causam a inibição de enzimas do citocromo P450; e Grupo 3: que não usavam antiepilépticos. A sedação foi induzida com midazolam (0,05 mg kg−1) e propofol (1 mg kg−1). Um adicional de 0,05 mg kg−1 de midazolam e resgate com 0,5 mg kg−1 de propofol foram administrados e repetidos para manter a sedação. A duração da sedação e a sedação adicional necessária foram comparadas. Resultados: A duração da dose inicial foi significativamente menor no Grupo I em comparação com os grupos II e III (p = 0,001, p = 0,003, respectivamente) e significativamente maior no Grupo II em comparação com os grupos I e III (p = 0,001, p = 0,029, respectivamente). A necessidade de midazolam adicional para sedação adequada foi maior no Grupo I em comparação com os grupos II e III (p = 0,010, p = 0,001, respectivamente). Além disso, a dose de resgate de propofol foi significativamente maior apenas no Grupo I em comparação com o Grupo III (p = 0,002). Conclusão: Em crianças epilépticas, a variabilidade ...

[The impact of different antiepileptic drugs on the sedation of children during magnetic resonance imaging]. / Impacto de diferentes medicamentos antiepilépticos na sedação de crianças durante a ressonância magnética.

BACKGROUND AND OBJECTIVES: The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance imaging in epileptic children receiving antiepileptic drugs that cause either enzyme induction or inhibition. METHODS: In American Society of Anesthesiology I-II, 120 children aged 3-10 years were included. Group 1: children using antiepileptic drugs that cause cytochrome P450 enzyme induction; Group 2: those using antiepileptic drugs that cause inhibition; and Group 3: those that did not use antiepileptic drugs. Sedation was induced with the use of 0.05 mg kg(-1) midazolam and 1 mg kg(-1) propofol. An additional 0.05 mg kg(-1) of midazolam and rescue propofol (0.5 mg kg(-1)) were administered and repeated to maintain sedation. The duration of sedation and the additional sedation needed were compared. RESULTS: The duration of the initial dose was significantly shorter in Group I compared with groups II and III (p = 0.001, p = 0.003, respectively). It was significantly longer in Group II compared with groups I and III (p = 0.001, p = 0.029, respectively). The additional midazolam needed for adequate sedation was increased in Group I when compared with groups II and III (p = 0.010, p = 0.001, respectively). In addition, the rescue propofol dose was significantly higher only in Group I when compared with Group III (p = 0.002). CONCLUSION: In epileptic children, the response variability to the initial sedative agents during the magnetic resonance imaging procedure resulting from the inhibition or induction of the cytochrome P450 isoenzymes by the antiepileptic drugs mandated the titration of anesthetic agents.

[The development of ventricular fibrillation due to etomidate for anesthetic induction: a very rare side effect, case report]. / Desenvolvimento de fibrilação ventricular por causa de etomidato para indução anestésica: um efeito colateral muito raro, relato de caso.

BACKGROUND AND OBJECTIVES: Ventricular fibrillation occurring in a patient can result in unexpected complications. Here, our aim is to present a case of ventricular fibrillation occurring immediately after anesthesia induction with etomidate administration. CASE REPORT: A fifty-six-year-old female patient with a pre-diagnosis of gallstones was admitted to the operating room for laparoscopic cholecystectomy. The induction was performed by etomidate with a bolus dose of 0.3mg/kg. Severe and fast adduction appeared in the patient's arms immediately after induction. A tachycardia with wide QRS and ventricular rate 188beat/min was detected on the monitor. The rhythm turned to VF during the preparation of cardioversion. Immediately we performed defibrillation to the patient. Sinus rhythm was obtained. It was decided to postpone the operation due to the patient's unstable condition. CONCLUSION: In addition to other known side effects of etomidate, very rarely, ventricular tachycardia and fibrillation can be also seen. To the best of our knowledge, this is the first case regarding etomidate causing VF in the literature.

Ameliorating effects of CAPE on oxidative damage caused by pneumoperitoneum in rat lung tissue.

We investigated the biochemical and histopathological effects of caffeic acid phenethyl ester (CAPE) against oxidative stress causing lung injury induced by pneumoperitoneum. Twenty-eight rats were selected at random and seven rats were assigned to each of the following groups. The control group (S) was subjected to a sham operation without pneumoperitoneum. The other groups were subjected to CO2 pneumoperitoneum 15 mmHg for 60 min. The laparoscopy group (L) had no additional drugs administered, the laparoscopy + alcohol (LA) group had 1 ml of 70% ethyl alcohol administered 1 h before the desufflation period, and the laparoscopy + CAPE (LC) group had CAPE administered at 10 µmol/kg 1 h before the desufflation period. The total oxidative status levels of lung and plasma were significantly increased in the LA group as compared with the LC and S group. When the LC group was compared with the L group, there was a decrease in the level of total oxidant status and increase in the levels of total antioxidant status and paraoxonase in lung tissue. The level of total antioxidative status in the S group was increased compared with the L group in lung tissue and bronchoalveolar lavage fluid. TNF-α and IL-6 were found significantly elevated in the L group compared with the LC and S groups in bronchoalveolar lavage fluid. There was a similar increase in plasma levels of IL-6. These results were supported by histopathological examination. CAPE was found to considerably reduce oxidative stress and inflammation induced by pneumoperitoneum.

Oral intralipid emulsion use: a novel therapeutic approach to pancreatic ß-cell injury caused by malathion toxicity in rats.

We aimed to investigate whether oral intralipid emulsion (OIE) reduces pancreatic ß-cell injury (PßCI) by chelating with malathion (M), or increases PßCI by increasing M absorption in the stomach. Fifty rats were randomly divided into six groups: control group (C); OIE administered group (L); M-treated group (M); OIE-administered group immediately after given M (M0L); OIE-administered group 6 hours after being given M (M6L) and OIE administered group 12 hours after being given M (M12L). M induced PßCI, hyperglycemia, temporary hyperinsulinemia and oxidative stress (OS). However, there was no significant difference in serum levels of glucose, insulin, total oxidants (TOS) and liver TOS between the M0L group and groups C and L. Also, insulin levels of M12L significantly increased, compared to the M6L group. Biochemical results, which were confirmed by histopathology, indicate that administering OIE after 6 hours and immediately after taking M may markedly prevent PßCI, hyperglycemia and OS. In addition, OIE's effectiveness decreased after 6 hours and was totally ineffective after 12 hours. We concluded that OIE may help to achieve a better prognosis and reduce mortality rate in cases presented to the emergency department, particularly within the first 6 hours, resulting from organophosphate pesticide poisoning by oral ingestion.

The effect of gender on the early results of coronary artery bypass surgery in the younger patients' group.

INTRODUCTION: In this retrospective study, we aimed to determine the risk factors for coronary artery bypass surgery in patients under 45 years of age, and evaluate the early postoperative results and the effect of gender. METHODS: A total of 324 patients under 45 years of age who undergone on-pump coronary artery bypass surgery between April 12, 2004 and January 10, 2012 were included to the study. Patients divided into groups as follows: Group 1 consisted of 269 males (mean age 41.3), Group 2 consisted of 55 females (mean age 41.6). Preoperative risk factors, intraoperative and postoperative data and early mortality rates of the groups were compared. RESULTS: Smoking rate was significantly higher in Group 1. Diabetes mellitus incidence and body mass index were significantly higher in Group 2 (P values P=0.01; P=0.0001; P=0.04 respectively). The aortic cross-clamping and cardiopulmonary bypass time and number of grafts per patient were significantly higher in Group 1 (P values P=0.04; P=0.04; P=0.002 respectively). There were no deaths in either group. CONCLUSION: We found that gender has no effect on early mortality rates of the coronary bypass surgery patients under 45 years.

Perioperative Anaesthetic Approach in a Homozygous Sickle Cell Anaemia Patient with Frequent Pain Crises.

Sickle cell disease (HbS) is a haemolytic anaemia characterized by the formation of abnormal haemoglobin. In patients with sickle cell disease, high rates of erythrocyte generation, degradation, and hyperbilirubinemia increase the risk for cholelithiasis. Previous studies have found that the incidence of cholelithiasis is 70% in adult patients. In sickle cell disease, decreased oxygen concentration leads to the sickling of erythrocytes by causing aggregation and polymerization. Sickle erythrocytes can have devastating effects on many vital organs by causing microvascular occlusion. In patients with sickle cell anaemia, anaesthetic technique, anaesthetic agents, and surgical trauma may cause additional risk. In this case report, we present a perioperative anaesthetic approach in the laparoscopic cholecystectomy of a patient with HbS, elevated liver function tests, and frequent pain crises.
