In adults, diaphragmatic eventration causes respiratory impairment that is associated with severe dyspnea, orthopnea and hypoxia. Most of the symptomatic patients may survive with supportive therapy without any need for surgical correction, though they are at risk of spontaneous diaphragm rupture. Spontaneous diaphragmatic rupture may develop in a patient with diaphragmatic eventration as a result of any event that leads to increase in intraabdominal pressure. In this case report, we present the anesthetic management of an adult patient with congenital diaphragmatic eventration undergoing craniotomy operation.

Respiratory functions are frequently deteriorated due to hypoplasia of oropharyngeal and nasopharyngeal cavities. Obstructive sleep apne syndrome, cor pulmonale and sudden death syndrome are among the complications of Apert syndrome. All of these anatomical and physiopathological disorders in the airways lead to a significant concern during anesthesia practice. Difficulty in mask ventilation, difficult intubation and postoperative airway obstruction may be seen in these patients. In this case report we present our anesthetic experience in an infant with Apert syndrome whom anesthesia was given for tracheostomy and difficult intubation was encountered.

Materials and methods: Right and left SGBs were performed with 8 mL of 0.5% bupivacaine in 10 patients with primary Raynaud's phenomenon. Th ere was an interval of at least 1 week between the right and left blocks of each patient. Th e blood pressure and the RR and QT intervals were measured before the block and 5, 10, 15, 20, and 30 min aft er the block. Th e QTc interval was calculated using Bazett's formula. Results: Th e RR and QT intervals were longer 20 and 30 min aft er right SGB when compared with the preblock value (P = 0.037 for RR and P = 0.008 for QT). Th e QT and QTc intervals 20 and 30 min aft er left SGB were shorter than the preblock values (P = 0.011, P = 0.012 for QT; P = 0.013, P = 0.009 for QTc). Conclusion: We conclude that right SGB prolongs the RR and QT intervals while left SGB shortens the QT and QTc intervals in patients with primary Raynaud's phenomenon. Precautions must be taken, taking into account the risk of fatal arrhythmia following right SGB.

Eighty Wistar rats were divided into 4 groups. After the flap elevation, in group 1, the flaps were sutured back without ischemic insult. Groups 2, 3, and 4 were exposed to ischemia for 12 hours. In groups 1 and 2, saline, in group 3, 10 μg/kg dexmedetomidine, and in group 4, 30 μg/kg dexmedetomidine were administered i.p. 45 minutes before I/R periods. Each group was subdivided further into 2 equal groups (a and b). Tissue samples of groups 1a, 2a, 3a, and 4a were obtained 12 hours after the reperfusion, and those of groups 1b, 2b, 3b, and 4b were obtained after 7 days. The necrotic areas were also calculated. Nitric oxide, malondialdehyde (MDA), and myeloperoxidase (MPO) activity were assessed in the tissue samples. Nitric oxide, MDA, and MPO activity levels in group 2a were significantly higher those in group 1a (P &amp;amp;lt; 0.05). The levels in groups 3a and 4a were lower than those in group 2a (P &amp;amp;lt; 0.05). Nitric oxide, MDA, and MPO activity levels were significantly higher in group 2b compared with group 1b (P &amp;amp;lt; 0.05). The levels were lower in Groups 3b and 4b compared with group 2b (P &amp;amp;lt; 0.05). Flap necrosis area was significantly lower in groups 3b and 4b than that in group 2b (P &amp;amp;lt; 0.05). We conclude that administering dexmedetomidine before I/R periods can reduce ischemia-reperfusion injury of flaps, and it has a beneficial effect on flap survival.

The aim of this study is to investigate the effect of II-IH nerve block on postoperative pain and analgesic consumption in patients when performed after CS. METHODS: Sixty ASA I-II patients, scheduled for elective CS were included in the study. After general anaesthesia, patients were allocated into 2 groups randomly. In group I bilateral II-IH block has been performed after the skin closure, with 10 ml of 0.5% ropivacaine on each side. In group II sham block had been performed. For postoperative analgesia all patients received tramadol via i.v patient controlled analgesia. Visual analogue scale (VAS) scored tramadol consumption and side effects. RESULTS: The mean VAS scores in II-IH block group were significantly lower than in sham block group at 6 th , 8 th , 12 th , 24 th hours at rest (p < 0.05) and at 6 th , 8 th hours with movement (p < 0.05). Tramadol usage in II-IH block group was significantly less than in sham block group at all estimated time intervals (p < 0.05). Total tramadol consumption was 331 ± 82 mg in II-IH block group and 622 ± 107 mg in sham block group (p < 0.05). CONCLUSIONS: It was observed that II-IH nerve block when performed after the surgery may reduce analgesic consumption after CS.

This study was conducted in order to compare the effects of dexmedetomidine on hemodynamic response to tracheal intubation in hypertensive patients with esmolol and sufentanyl. Sixty hypertensive patients scheduled for noncardiac surgery under general anesthesia were randomly assigned to receive one of the three drugs before induction of anesthesia. Groups I, II, and III respectively received esmolol (100 mg) dexmedetomidine (1 μg/kg) and sufentanyl (0.25 μg/kg). Heart Rate (HR), systolic (SAP) and diastolic (DAP) arterial pressures were recorded before drug administration (baseline; T1), after drug administration (T2), after induction of anesthesia (T3), immediately after intubation (T4) and 3, 5 and 10 minutes after intubation (T5, T6, and T7, respectively). The mean percentage variations from T1 to T4 were calculated for all variables (HR, SAP and DAP). Thiopental dose, onset t...

Research paper thumbnail of The efficacy of ilioinguinal and iliohypogastric nerve block for postoperative pain after caesarean section

The aim of this study is to investigate the effect of II-IH nerve block on postoperative pain and analgesic consumption in patients when performed after CS. Sixty ASA I- II patients, scheduled for elective CS were included in the study. After general anaesthesia, patients were allocated into 2 groups randomly. In group I bilateral II-IH block has been performed after the skin closure, with 10 ml of 0.5% ropivacaine on each side. In group II sham block had been performed. For postoperative analgesia all patients received tramadol via i.v patient controlled analgesia. Visual analogue scale (VAS) scored tramadol consumption and side effects. The mean VAS scores in II-IH block group were significantly lower than in sham block group at 6(th), 8(th), 12(th), 24(...

Research paper thumbnail of Anesthesia for tracheostomy in an infant with Apert syndrome

Gaziantep Medical Journal, 2013

Respiratory functions are frequently deteriorated due to hypoplasia of oropharyngeal and nasopharyngeal cavities. Obstructive sleep apne syndrome, cor pulmonale and sudden death syndrome are among the complications of Apert syndrome. All of these anatomical and physiopathological disorders in the airways lead to a significant concern during anesthesia practice. Difficulty in mask ventilation, difficult intubation and postoperative airway obstruction may be seen in these patients. In this case report we present our anesthetic experience in an infant with Apert syndrome whom anesthesia was given for tracheostomy and difficult intubation was encountered.

Materials and methods: Right and left SGBs were performed with 8 mL of 0.5% bupivacaine in 10 patients with primary Raynaud's phenomenon. Th ere was an interval of at least 1 week between the right and left blocks of each patient. Th e blood pressure and the RR and QT intervals were measured before the block and 5, 10, 15, 20, and 30 min aft er the block. Th e QTc interval was calculated using Bazett's formula. Results: Th e RR and QT intervals were longer 20 and 30 min aft er right SGB when compared with the preblock value (P = 0.037 for RR and P = 0.008 for QT). Th e QT and QTc intervals 20 and 30 min aft er left SGB were shorter than the preblock values (P = 0.011, P = 0.012 for QT; P = 0.013, P = 0.009 for QTc). Conclusion: We conclude that right SGB prolongs the RR and QT intervals while left SGB shortens the QT and QTc intervals in patients with primary Raynaud's phenomenon. Precautions must be taken, taking into account the risk of fatal arrhythmia following right SGB.

Eighty Wistar rats were divided into 4 groups. After the flap elevation, in group 1, the flaps were sutured back without ischemic insult. Groups 2, 3, and 4 were exposed to ischemia for 12 hours. In groups 1 and 2, saline, in group 3, 10 μg/kg dexmedetomidine, and in group 4, 30 μg/kg dexmedetomidine were administered i.p. 45 minutes before I/R periods. Each group was subdivided further into 2 equal groups (a and b). Tissue samples of groups 1a, 2a, 3a, and 4a were obtained 12 hours after the reperfusion, and those of groups 1b, 2b, 3b, and 4b were obtained after 7 days. The necrotic areas were also calculated. Nitric oxide, malondialdehyde (MDA), and myeloperoxidase (MPO) activity were assessed in the tissue samples. Nitric oxide, MDA, and MPO activity levels in group 2a were significantly higher those in group 1a (P &amp;amp;lt; 0.05). The levels in groups 3a and 4a were lower than those in group 2a (P &amp;amp;lt; 0.05). Nitric oxide, MDA, and MPO activity levels were significantly higher in group 2b compared with group 1b (P &amp;amp;lt; 0.05). The levels were lower in Groups 3b and 4b compared with group 2b (P &amp;amp;lt; 0.05). Flap necrosis area was significantly lower in groups 3b and 4b than that in group 2b (P &amp;amp;lt; 0.05). We conclude that administering dexmedetomidine before I/R periods can reduce ischemia-reperfusion injury of flaps, and it has a beneficial effect on flap survival.
