    Evaluation of the effectiveness of fentanyl, tramadol and diclofenac in combination with propofol for dilation and curettage
    (Galenos Yayincilik, 2006) Demiraran, Yavuz; Somunkiran, Asli; Sezen, Gulbin; Kocaman, Buket; Hayit, Feray; Ozdemir, Ismail
    Objective: To compare the value of three agents in terms of providing postoperative analgesia in patients having dilation and curettages. Their effects on hemodynamic parameters were evaluated. Recovery and sedation properties were also assessed. Design: Prospective, randomized trial Setting: University hospital Patients: Sixty three patients who underwent fractional curettage. Interventions: Diclofenac 1 mg/kg intramuscularly 30 minutes before induction and tramadol 1 mg/kg intravenously 15 minutes before induction were given in group 1 and 2, respectively. The third group received fentanyl 1 mu g/kg intravenously for induction. Then, induction was provided with propofol 2 mg/kg and % 50 air and % 50 oxygen given with face mask. For anesthesia management 20% of the induction dose of propofol was used intermittently. Main outcome measures: Peroperative and postoperative haemodynamic parameters and SPO2 were recorded. Visual Analog Scale 0-10 cm, sedation score 0-4 point, Aldrete recovery scores 1-10 were assessed postoperatively at the 1, 5, 15, 30, and 120th minutes. Results: Peroperative and postoperative hemodynamic parameters showed no difference. The scores obtained by using Visual Analog Scale were also similar in all groups. There were no differences in sedation and Aldrete recovery scores in the three groups. On the other hand, propofol consumption was significantly lower in the fentanyl group when compared with the other two groups. Conclusion: Fentanyl usage decreased the amount of propofol when compared with diclofenac and tramadol administration. However, both tramadol and diclofenac were associated with lower amount of supplementary analgesic agents. They are both nonnarcotic analgesics. Therefore, preference of these two agents may be regarded more favorable.

    The Importance of the Trigeminal Cardiac Reflex in Rhinoplasty Surgery
    (Lippincott Williams & Wilkins, 2015) Ozcelik, Derya; Toplu, Gaye; Turkseven, Arzu; Sezen, Gulbin; Ankarali, Handan
    Background Trigeminocardiac reflex (TCR) consists of bradycardia or asystole along with hypotension and apnea coinciding with stimulation of the trigeminal nerve. During rhinoplasty procedures, we noticed that local anesthetic solution (LAS) application to the columellar area results in bradycardia. We planned to conduct a randomized prospective study on 47 patients undergoing rhinoplasty to demonstrate the characteristics of TCR arising from the columella. Method Local anesthetic solution containing 2% prilocaine with 1:80,000 adrenaline was applied under standard general anesthesia protocol. In group 1 (study group, n = 24), 2 mL of LAS was applied to the columella. In group 2 (control group, n = 23), 2 mL of LAS was applied to the nasal dorsum. In group 3 (control group, n = 20), after LAS was applied to nasal dorsum in group 2, we waited for 10 minutes. Then, 2 mL of LAS was applied to the columella. Here, recordings were taken for the columella. Heart rate (HR) and blood pressure (BP) were recorded just before needle insertion (baseline level), at the time of needle insertion (NIT) to the columella or dorsum, and after the 1st, 5th, 10th, 30th, and 60th seconds. Results Transient bradycardia (>= 20% drop in HR) was observed in 33% of the patients in group 1. Decrease in HR compared to the baseline level in group 1 was significantly greater than that of groups 2 and 3 at all times (P <= 0.05). Systolic BP in NIT and in 60th second in group 1, only in NIT in group 2 was significantly lower than that of baseline levels (P <= 0.05). Conclusions We concluded that stimulation of a sensory branch of the trigeminal nerve in the columellar area leads to TCR under general anesthesia by eliciting clinical hypotension with a drop in systolic BP and in HR of more than 20% compared to the baseline level. Knowing the existence of a certain TCR area will be helpful to the surgeon and anesthesiologist to exercise extra vigilance and to make continuous and meticulous monitoring of the electrocardiogram, HR, and BP during which the TCR may be precipitated such as local anesthetic infiltration to the columellar area in rhinoseptoplasty operations.
