CONTEXT Endotracheal tube cuff pressure (ETCP) is recommended to be maintained between 20-30 cm H2O limits. While insufficient inflation of ETC may cause aspirations, over-inflation of it may lead to damage in tracheal epithelium. AIMS We planned to investigate the effects of user experience and cuff pressure inflation method differences following endotracheal tube cuff pressure and complaints about it. PATIENTS AND METHODS Two hundred and fifty patients planned for general anaesthesia were included in this study. ETC was inflated by users with different experience according to leakage or pilot balloon palpation techniques. ETCPs were measured by manometer at three periods (5 and 60 minutes after endotracheal intubation, and before extubation). Complaints about it were recorded in post anaesthetic care unit and 24 hours postoperatively. RESULTS Though we found experience of user had significant effect on the ETCP regulations, we observed inflation methods did not have any effect. However we found ETCP was higher than normal range with experienced users. A correlation was observed between cuff pressure and anaesthesia duration with postoperative complaints. CONCLUSIONS Our study concluded that the methods used do not have any significant advantage over one another. While ETC inflated at normal pressure increases as users experience increases, experience alone is not enough in adjusting ETCP. A manometer should be used in routine inflation of ETC instead of conventional methods. CP and anaesthesia duration have correlations with some postoperative complaints.

Transurethral resection of prostate (TURP) syndrome is a complication characterised by symptoms changing from an asymptomatic hyponatremic state to convulsions, coma and death due to absorption of irrigation fluid during TURP. The syndrome appears to be related to the amount of fluid that enters the circulation via the blood vessels in the resection area. The first step in the course of action for therapy is to control bleeding and suspend the operation. In the case presented, we aimed to emphasise the importance of an early diagnosis and treatment of TURP syndrome in a patient that developed hyponatremia (90 mmol/l) while under general anaesthesia during a TURP procedure. In addition, multiple cystoscopic applications in the same session may facilitate development of the TURP syndrome.

Abstract Aim: To compare the efficiency of endouterine hemostatic square suture and the Bakri balloon tamponade in the treatment of bleeding due to complete placenta previa (CPP). Methods: Thirteen patients with the diagnosis of CPP and intractable bleeding were randomly divided into two groups in a single blind study. Group 1 (n=6) included patients in whom endouterine hemostatic square suture was applied, while group 2 (n=7) included patients in whom Bakri balloon tamponade was applied. The two groups were compared according to the maternal outcomes, the duration of caesarean section, the preoperative and the postoperative hemoglobin and hematocrit (Htc) values, the intraoperative and postoperative blood loss, as well as the newborn characteristics. Results: The duration of operation and the amount of intraoperative bleeding were significantly higher in group 1 (time: 78.3±8.1 vs. 62.8±3.9 min; P<0.05; intraoperative bleeding: 1946±242 vs. 1520±92 mL; P<0.05). The postoperative 24th h Htc values were found to be significantly lower in group 1 than in group 2 (25.6±3.7 vs. 29.5±1.3 g/dL; P<0.05). The postoperative blood loss was higher in group 1 than in group 2. (351±70 vs. 120±56 mL; P<0.05). Conclusion: There are two methods that are effective in preventing bleeding in CPP. However, the Bakri balloon tamponade may be a better alternative due to a shorter operation time and less blood loss.

Posterior reversible encephalopathy syndrome (PRES) is a temporary condition that is diagnosed clinically, neurologically, and radiologically. Its symptoms vary, and nonspecific headaches, confusion, impairment of consciousness, nausea, vomiting, and visual impairment may occur. Acute hypertension often accompanies these symptoms. Patients can also suffer from convulsions, cortical visual impairment, and coma. Diagnosis can be difficult due to focal neurologic signs. Nevertheless, knowing the clinical risk factors can lead to the right diagnosis. It has been reported that this condition may also occur during organ transplantation, immunosuppressive treatment, and autoimmune diseases and chemotherapy, and also patients with eclampsia. In this paper, a 21-year-old, 31-week pregnant woman, who had been diagnosed with PRES and thanks to early diagnosis and treatment had fully recovered and discharged from the intensive care unit, is presented, and the relevant literature is discussed.

AIM To evaluate the effects of three different doses of gabapentin pretreatment on the incidence and severity of myoclonic movements linked to etomidate injection. METHOD One hundered patients, between 18 and 60 years of age and risk category American Society of Anesthesiologists I-II, with planned elective surgery under general anesthetic were included in the study. The patients were randomly divided into four groups and 2h before the operation were given oral capsules of placebo (Group P, n=25), 400mg gabapentin (Group G400, n=25), 800mg gabapentin (Group G800, n=25) or 1200mg gabapentin (Group G1200, n=25). Side effects before the operation were recorded. After preoxygenation for anesthesia induction 0.3mgkg(-1) etomidate was administered for 10s. A single anesthetist with no knowledge of the study medication evaluated sedation and myoclonic movements on a scale between 0 and 3. Two minutes after induction, 2μgkg(-1) fentanyl and 0.8mgkg(-1) rocuronium were administered for tracheal intubation. RESULTS Demographic data were similar. Incidence and severity of myoclonus in Group G1200 and Group G800 were significantly lower than in Group P; sedation incidence and level were appreciably higher compared to Group P and Group G400. While there was no difference in the incidence of myoclonus between Group P and Group G400, the severity of myoclonus in Group G400 was lower than in the placebo group. In the two-hour period before induction other than sedation none of the side effects related to gabapentin were observed in any patient. CONCLUSION Pretreatment with 800mg and 1200mg gabapentin 2h before the operation increased the level of sedation and reduced the incidence and severity of myoclonic movements due to etomidate.

Abstract Objective: To determine the serum tenascin-C (TN-C) levels in cases with mild and severe preeclampsia. Methods: Pregnant women were divided into three groups, namely healthy pregnants (Group 1, n = 20), pregnants with mild preeclampsia (Group 2, n = 20) and pregnants with severe preeclampsia (Group 3, n = 20). The groups were formed so as to match each other in terms of gestational week. From each pregnant woman, pre- and post-delivery blood samples were obtained to measure serum TN-C levels. The data were evaluated using the Kruskall–Wallis variance analysis. For the obtained values of p < 0.05, the groups were compared in pairs. A p value of < 0.017 was accepted as significant. Results: In Groups 1, 2 and 3, the prepartum TN-C levels were 5.02 ± 0.4 µg/ml, 12.8 ± 2.9 µg/ml and 33.8 ± 11.7 µg/ml, and in the postpartum TN-C levels were 4.7 ± 0.1 µg/ml, 11.7 ± 1.8 µg/ml and 50.6 ± 33.8 µg/ml, respectively. There was a significant difference between the groups in terms of the prepartum and postpartum TN-C levels (p < 0.017, Mann–Whitney U [MWU] test). There was also a significant difference in the prepartum TN-C levels between Groups 2 and 3 (p < 0.017, MWU test). Conclusions: The prepartum and postpartum TN-C levels were significantly higher in mild and severe preeclampsia than those in healthy pregnants.

) in Group II (P > 0.05). A correlation was observed between cost and operation times (P = 0.002, r = 0.158). CONCLUSIONS Although a statistical difference was not established in this study in terms of time and costs in appendectomy operations conducted as open and laparoscopically, changes may occur in time in market conditions of drugs, patent rights, legal regulations, and prices. Therefore, we believe that it would be beneficial to update and revise cost analyses from time to time.
