Comparison of effectiveness of intubation by way of “Gum Elastic Bougie” and “Intubating Laryngeal Mask Airway” in endotracheal intubation of patients with simulated cervical trauma

Purpose: In this study, we evaluated the effectiveness of intubations by way of “Gum Elastic Bougie” and “Intubating Laryngeal Mask Airway” in endotracheal intubation of patients with simulated cervical trauma. Method: 134 patients were included in the study. All patients were placed cervical collar for a simulated cervical trauma. Patients were allocated randomly into three groups: Group NI (n = 45) intubation with Macintosh laryngoscopy, Group GEB (n = 45) intubation with Gum Elastic Bougie, and Group ILMA (n = 44) intubation with Intubating Laryngeal Mask Airway. The number of intubation attempts, success of intubation, duration of complete visualization of the larynx, duration of intubation, user's performance score, hemodynamic changes and the observed complications were recorded. Results: Success of intubation in the first attempt was highest in Group GEB while it was lowest in Group ILMA. Regarding the intubation success, rates of successful intubation were 95.6%, 84.4% and 65.9% in Groups GEB, NI, and ILMA, respectively. Durations of visualization of larynx and intubation were shorter in Groups NI and GEB than in Group ILMA. This difference was statistically significant (p < 0.05) while there was no significant difference between Groups NI and GEB. The number of patients with “good” intubation performance was significantly higher in Group GEB while the number of patients with “poor” intubation performance was significantly higher in Group ILMA (p < 0.05). Conclusions: We conclude that GEB, which is cheap and easily accessible, should be an advantageous choice in cervical trauma patients for both the easeness of intubation and patient morbidity and mortality. Resumo: Objetivo: Neste estudo avaliamos a eficácia de intubações por meio de guia introdutor Bougie e máscara laríngea em intubação endotraqueal de pacientes com trauma cervical simulado. Método: Foram incluídos no estudo 134 pacientes. Colar cervical foi colocado em todos os pacientes para um trauma cervical simulado. Os pacientes foram alocados aleatoriamente em três grupos: Grupo NI (n = 45) foi submetido à intubação com laringoscópio Macintosh; Grupo ITE (n = 45) foi submetido à intubação com guia introdutor de tubo endotraqueal e Grupo ML (n = 44) foi submetido à intubação com máscara laríngea. Número de tentativas de intubação, sucesso de intubação, tempo de visualização completa da laringe, tempo de intubação, escore de desempenho do usuário, alterações hemodinâmicas e complicações observadas foram registrados. Resultados: O sucesso da intubação na primeira tentativa foi maior no Grupo ITE e menor no grupo ML. Ainda em relação ao sucesso da intubação, as taxas de sucesso foram 95,6%, 84,4% e 65,9% nos grupos ITE, NI e ML, respectivamente. Os tempos de visualização da laringe e de intubação foram menores nos grupos NI e ITE que no Grupo ML. Essa diferença foi estatisticamente significativa, p < 0,05), enquanto não houve diferença significativa entre os Grupos NI e ITE. O número de pacientes com bom desempenho na intubação foi significativamente maior no grupo ITE, enquanto o número de pacientes com mau desempenho na intubação foi significativamente maior no grupo ML (p < 0,05). Conclusões: Concluímos que o ITE, que é barato e facilmente acessível, deve ser uma opção vantajosa em pacientes com trauma cervical, tanto pela facilidade de intubação quanto devido à taxa de morbidade e mortalidade dos pacientes.

The Effects on Sensorial Block, Motor Block, and Haemodynamics of Levobupivacaine at Different Temperatures Applied in the Subarachnoid Space

Aim. To evaluate the effects of 0.5% levobupivacaine at 37°C preheated from room temperature, on sensorial block, motor block, and haemodynamics in patients undergoing transurethral prostate resection (TUR-P). Material and Method. The patients were randomly allocated to two groups: Group I patients were injected with 3 mL 0.5% levobupivacaine solution which had been kept at room temperature for at least 24 hours and Group II patients were injected with 3 mL 0.5% levobupivacaine solution which had been kept at 37°C for at least 24 hours. The patients were examined in terms of sensorial block, motor block, haemodynamic profile, and incidence of side effects. Results. No significant difference was found between the groups in terms of demographic data. The time to reach T10 sensory block and the time of starting motor block were found to be significantly shorter in Group II . The duration of sensory block over T10 and T6, the duration of L1 regression, the duration of the sensory block, and the regression time of the motor blocks from 3 to 2 were found to be longer in Group II. Conclusion. The use of 0.5% levobupivacaine spinal anaesthesia heated to 37°C accelerated the start of sensory and motor block

Histological and electron microscopic examination of the effect of Dexketoprofen Trometamol on liver in rats

WOS: 000413375800008Background: The current study was performed for histological and electron microscopic examination of the effects of different doses of dexketoprofen trometamol on liver in rats. Material and Methods: Shame group consisted of rats administered 1 ml of 0.9% NaCl twice a day via intraperitoneal route, 8 mg/kg/day was used in Dexketoprofen Trometamol low-dose group, and 16 mg/kg/day was used in Dexketoprofen Trometamol high-dose group. 30 healthy Wistar albino type male rats were used in the study as animal materials. Results: The presence of TUNEL positive cells was increased with the increasing dose level of Dexketoprofen Trometamol and TUNEL positive hepatocytes distributed all over the tissue. Diffuse degeneration was determined in the liver sections of the group administered high-dose. Necrotic areas became more apparent particularly in regions close to the central vein. PCNA involvement was detected to be considerably increased compared to the shame and low-dose groups. Electron microscopic image of liver in the group administered high-dose drug showed that all hepatocytes present with highly active cell structure. Hepatocyte mitochondria were observed to be highly developed and to grow large and fuse from place to place. Granulated and smooth endoplasmic reticulum tubulus and cisternae displayed a highly-dilated appearance. Bile canaliculi were distinguished as dilated and its lumen was covered with microvilli. There were many vacuolar formation in addition to lipid droplets in the cytoplasms of ito cells. Conclusion: Dexketroprofen Trometamol drug administration was determined to increase activation particularly in parenchymal cells depending on dose and cause degeneration in liver tissue with heavy activity
