Background: In our study, we aimed to compare the endotracheal intubation conditions without muscle relaxants during induction with the combinations of dexmedotimidine-propofol, dexmedotimidine-thiopenthal and dexmedetomidine-etomidate. Method: Seventy-six patients, in ASA risk group I-II, between ages 20-60 years, with Mallampati Class 1 were included in the study. All patients were premedicated with midazolam. The patients were randomly divided into three groups as Group P (n=30, dexmedetomidine-propofol), Group T (n=30, dexmedetomidine-thiopenthal), Group E (n=16, dexmedetomidine-etomidate). All patients received dexmedetomidine 1 μg.kg-1 in 10 min. Then, the patients were administered 2.5 mg.kg-1 propofol for Group P, 5 mg.kg-1 thiopental for Group T and 0.3 mg.kg-1 etomidate for Group E during induction. Hemodynamic data of the patients were recorded before induction, after dexmedetomidine administration, immediately after intubation and 3, 5 and 10 minutes after intubation. Results: There was no difference between the groups according to hemodynamic data. Sixteen patients in Group P and 10 patients in Group T had acceptable intubation conditions. Muscle relaxant was needed in 14, 20 and 16 patients in Groups P, T and E, respectively (p<0.05). Conclusion: In conclusion, we determined that best intubation conditions without muscle relaxants were achieved with propofol-dexmedetomidine combination. None of the patients receiving etomidate-dexmedetomidine combination could be intubated without muscle relaxants (Tab. 6, Ref. 29).
Background: The aim of this prospective, randomized, controlled study was to evaluate the analgesic effect of US-guided Pectoral (PECS) I blocks on postoperative analgesia after TIVAP insertion. Methods: A hundred-twenty patients were included in this study. The patients were divided into two groups: Group PECS and Group INF (infiltration). A total 0.4 mL kg−1 0.25% bupivacaine was injected to below the middle of the clavicle in the interfascial space between the pectoralis major and minor muscles for PECS-1. The skin and deep tissue infiltration of the anterior chest wall was performed with 0.4 mL kg−1 0.25% bupivacaine for INF group. Tramadol and paracetamol consumption, visual analog scale pain scores were recorded at 0, 1, 4, 12, and 24 h postoperatively. Results: The use of the PECS in TIVAP significantly decreased the amount of paracetamol used in the first 24 h postoperatively ( p < 0.001). There was a statistically significant difference in the number of tramadol rescue analgesia administered between the groups ( p < 0.001) There was no significant difference between the groups in terms of the VAS scores at 0 and 24 h. However, VAS scores at 1, 4, and 12 h were found to be significantly lower in patients who underwent PECS than in those who received infiltration anesthesia ( p < 0.001). Conclusions: This study shows that US-guided PECS-1 provides adequate analgesia following TIVAP insertion as part of multimodal analgesia. The PECS-1 significantly reduced opioid consumption.
Objectives:To observe the effect of different fresh gas flows (FGF) on carboxyhemoglobin (COHb) levels non-invasively and continuously and to determine the contribution of the smoking status to intraoperative carbon monoxide (CO) accumulation and respiratory complications.Methods: A total of 64 patients were included in the study. Carboxyhemoglobin level was monitored noninvasively from the fingertip. Patients were divided into 2 according to the FGF as low-flow anesthesia (LFA; Group L) and high flow anesthesia (Group H). Each group was divided again into 2 groups as smokers and non-smokers. Carboxyhemoglobin and
Original Articleand the respiratory complications that occurred in the post-anesthesia care unit were recorded.
Results:The mean COHb values were significantly higher in Group L between 30th and 210th minutes. Furthermore, in Group L, intraoperative COHb levels were significantly higher in smokers compared to non-smokers in all periods. In group H, no difference was observed between smokers and non-smokers in terms of COHb levels after 60 minutes and also preoperative COHb levels of the patients developed respiratory complication was higher.
Conclusion:If the CO 2 absorbent is properly preserved in patients who are administered LFA, there will be no risk of CO accumulation even in chronic smokers. ClinicalTrials.gov REG. No.: NCT04832256
