Thirty ASA I-II patients undergoing tympanoplasty were randomly assigned to remifentanil and alfentanil-sodium nitroprusside groups, equal in number. Anesthesia was induced with remifentanil or alfentanil combined with propofol and rocuronium, and maintained with remifentanil or alfentanil-sodium nitroprusside infusions combined with propofol. All patients were ventilated with a mixture of 33% O2 and 66% N2O. Invasive mean arterial blood pressure, heart rate, peripheral oxygen saturation, the amount of bleeding at surgical site, and blood gas values were recorded. Controlled hypotension was achieved at a target mean arterial pressure of 60+/-5 mmHg in both groups. Compared to the baseline levels, heart rate values were lower in the remifentanil group (p<0.05), and similar in the sodium nitroprusside group (p>0.05). The amo...

General anesthesia also has some disadvantages, especially with respect to airway control in patients with ankylosing spondylitis. We present herein a gravida with ankylosing spondylitis who had a cesarean delivery performed under spinal anesthesia. A 30-yr-old gravida at 38 weeks gestation with a 9 yr history of ankylosing spondylitis was admitted to our hospital in labor. She was scheduled for an elective repeat cesarean delivery. Spinal anesthesia was induced using a 22-gauge Quincke spinal needle with 1.8 mL of 0.5% heavy bupivacaine + 0.2 mL (10 microg) of fentanyl at the L3-4 interspace in the left lateral position by the median approach. Adequate sensory and motor blockade were achieved. The postoperative period was uneventful and she was discharged home on postoperative day 3. We suggest that spinal anesthesia can be safely and effectively used as an alternat...

Hip fractures are usually treated in hospital with surgery so these patients will need anaesthesia. The impact of anaesthetic techniques in patients experiencing hip fracture is controversial. This study was conducted to compare the effects of two anaestehic techniques: unilateral spinal and general anaesthesia on haemodynamy and postoperative cognitive disfunction (POCD) in elderly patients undergoing hip surgery. Fifty two American Society of Anesthesiologists (ASA) II-III patients, aged between 60-85 years, undergoing hip fracture repair were randomly allocated to receive; unilateral spinal anaesthesia with 7.5 mg 0.5 % hyperbaric bupivacaine (Group USpA, n=26) or general anaesthesia (Group GA, n=26). After maintaining the lateral position for 15 minutes sensorial block levels and motor block degrees were determined at 5, 15, 30 and 45 minutes in group USpA and haemodynamic parameters were determined a...

Study design: After the approval from Medical Ethics Committee and written informed consent, 30 parturients undergoing caesarean section operation, randomly allocated to receive either general anaesthesia (in Group GA) (n:15) or combined spinal epidural anaesthesia (Group CSEA) (n:15) were included the study. Non invasive arterial blood pressure, heart rate and peripheral oxygen saturation values were recorded before anaesthesia (baseline) and thereafter with 5 min intervals until at the end of surgical procedure. Following delivery, a segment of the umblical cord was doubtly clamped and umblical vein blood gas samples were taken and APGAR scores were recorded at 1 and 5 min. Results: Mean arterial blood pressure (MBP) and heart rate (HR) values were significantly higher in...

In our study we aimed to compare the effectiveness of Ringer lactate and hydroxy ethyl starch (HES) and their combination in prevention of spinal anaesthesia related hypotension. Study design: 60 patients undergoing inguinal hernia repair operation were allocated randomly to three groups to receive either; in Group I: 10 ml/kg Ringer lactate or in Group II: 10 ml/kg HES %6 or in Group III: 5 ml/kg Ringer lactate and 5 ml/kg HES %6 combination infused in 20 minutes before spinal anaesthesia. Systolic blood pressure (SBP) and heart rate (HR) values were followed. Hypotension was defined as a decrease of 30% or more below baseline values or

Most pathologic signs can be attributed to compression effect on intraabdominal organs, vascular structures and ascites made by tumor. After removal of such huge pelvic masses, serious clinical hypotension and inferior vena cava (IVC) syndrome can be seen related to the aspiration of high levels of fluid or resection of bulky mass. Here, we present four cases of bulky ovarian masses by means of gynecologic surgery, anaesthesia and pathology. Case: 54, 35, 39, 42 years old patients having 20 kg and 40x20cm; 14 kg and 40x40x40 cm, 17 kg and 45x50 cm and 53x50 cm adnexal masses respectively were operated. Histopathologies were found each to be the first two borderline mucinous carcinomas, third one was benign endometrioid tumor and the fourth one was mucinous cystadenoma complexed with teratom structures. On preoperative assessment, patients had dyspnea and tachypnea due to huge abdominal distention, blood g...

Methods: After the approval from Ethics Committee of our Hospital, 40 healthy parturients undergoing elective caserean section were allocated randomly into two groups after their informed consent was taken. Desflurane 3% in Group D or sevoflurane 1% in Group S were used in a 50% nitrous oxide and oxygen mixture for maintenance of anaesthesia. Systolic, diastolic, mean blood pressure, heart rate values and peripheral oxygen saturation were recorded as baseline and followed up with 5 min intervals peroperatively. Neonatal status was evaluated with APGAR scores at 1 and 5 min, umblical cord blood gas analysis, neurologic adaptive capacity scores at 2 and 24 h. Extubation and recovery times of the mother, haemoglobin and haematocrit values were recorded preoperatively and at postoperative 24.hours. Results: Blood pressure and heart r...

Methods: Sixty patients in ASA I-II physical status undergoing abdominal hysterectomy operation were randomly assigned to two groups as: planned to apply rocuronium 0.6 mg.kg-1 to extubate with clinical observation (Group R); atracurium 0.5 mg.kg-1 to extubate with clinical observation (Group A). At the end of the operation all patients were antagonized with neostigmine. TOF values at extubation and at 1., 3., 5., 10. minutes after extubation, operation and anaesthesia times, total fentanyl, neuromuscular blocker agent and neostigmine doses were recorded. Results: Demographic characteristics of the patients, duration of operation and anaesthesia, total fentanyl, neuromuscular blocker, neostigmine doses were similar in four groups. TOF ratio was

Still it can cause cardiovascular changes like hypotantion and bradycardia. So unilateral anaesthesia is prefered in high risk patients for less hemodynamic instability. We aimed to share our unilateral spinal anaesthesia experience in an ASA IV E patient with ejection fraction 28%.
