The Evaluation of Upper Airway Complications Secondary to Intubation: Cuff Pressure Manometer Versus Conventional Palpation Method.

OBJECTIVES: General anesthesia is preferred in most otorhinolaryngologic surgeries. The aim of the present study was to evaluate upper airway complications secondary to intubation including sore throat, cough, dysphonia, and dysphagia considering endotracheal tube (ET) cuff pressure, tube diameter, and duration of intubation. METHODS: After the assignment of 67 patients to the study and control groups, ET cuff pressure was adjusted to be between 20 and 30 cm H2O using a cuff pressure manometer in the study group. In the control group, the cuff pressure was decided by the anesthesiologist using the conventional palpation method. Sore throat, cough, dysphonia, and dysphagia were compared between the groups at 4, 8, and 24 h postoperatively. RESULTS: Cuff pressure was significantly higher in the control group than in the study group. In the control group, sore throat was more frequently observed at 4, 8, and 24 h, whereas in the study group, cough and dysphonia were more often observed at 4 and 8 h. At 4 and 8 h, cough was found to be related to the duration of intubation. CONCLUSION: Arrangement of cuff pressure using a cuff manometer is suggested to decrease complications of the upper airway secondary to intubation because of the higher rate of these complaints in patients whose cuff pressure is arranged by the conventional palpation method.

Effects of intra-articular levobupivacaine, fentanyl-levobupivacaine and tramadol-levobupivacaine for postoperative pain in arthroscopic knee surgery.

OBJECTIVE: The aim of this study was to compare the postoperative analgesic efficacy of intra-articularly injected levobupivacaine, levobupivacaine-fentanyl, and levobupivacaine-tramadol combinations. METHODS: Eighty patients scheduled for elective knee arthroscopy were divided randomly into 4 groups of 20 patients each. Group 1 (the control group) received intra-articular saline, Group 2 received levobupivacaine 2.5 mg/ml, Group 3 received levobupivacaine 2.5 mg/ml + tramadol 50 mg, and Group 4 received levobupivacaine 2.5 mg/ml + fentanyl l50 mcg. All patients were operated on under general anesthesia, and a total of 20 ml study solution was injected: 7 ml subcutaneously before surgery and 13 ml intra-articularly upon completion of surgery. For postoperative, pain visual analogue scale (VAS) was assessed at the 1st, 2nd, 4th, 8th, 12th, and 24th hours postoperatively. Patients with a VAS score over 5 received diclofenac sodium, and the need for rescue analgesics was recorded. RESULTS: At the 1st, 2nd, 4th, 8th, 12th, and 24th postoperative hours, Group 3 and Group 4 had statistically significant lower VAS scores of pain (p<0.01). Postoperative rescue analgesic requirements were different among the groups. The postoperative 1st hour analgesic requirement was statistically significantly lower in Group 3 and Group 4 when compared to the other groups (p<0.01). At the postoperative 2nd and 4th hours, analgesic requirements were statistically significantly lower in Group 3 than in the other groups (p<0.01). Analgesic requirements were statistically significantly lower in Group 3 and Group 4 than in the other groups (p<0.01). Analgesic requirements at the 12th and 24th postoperative hours did not show any statistically significant difference (p>0.05). CONCLUSION: The results indicated that levobupivacaine combined with either fentanyl or tramadol decreased rescue analgesic requirements when compared to levobupivacaine alone.

The Analgesic Effects of Morphine and Tramadol Added to Intra-articular Levobupivacaine-Tenoxicam Combination for Arthroscopic Knee Surgery on Postoperative Pain; a Randomized Clinical Trial.

BACKGROUND: Arthroscopic knee surgery is commonly performed as an outpatient procedure and is often associated with postoperative pain. OBJECTIVES: We aimed to compare the effects of intra-articular levobupivacaine-tenoxicam-tramadol and levobupivacaine-tenoxicam-morphine combinations on postoperative pain in patients undergoing elective arthroscopic knee surgery. MATERIALS AND METHODS: A total of 90 ASA I-II patients undergoing elective arthroscopic meniscectomy under general anesthesia were enrolled. The participants were randomly allocated to three groups to receive the following intra-articular medications after completion of the surgery and before deflation of the tourniquet: Group S, 20 mL of saline; Group T, 35 mg of levobupivacaine, 20 mg of tenoxicam, and 100 mg of tramadol in 20 mL saline; and Group M, 35 mg of levobupivacaine, 20 mg of tenoxicam, and 4 mg of morphine in 20 mL saline. Visual analogue scale values at rest (VASr) and at active flexion of knee (VASa) at postoperation hours 1, 2, 4, 8, 12, and 24, duration of analgesia, total analgesic consumption, and number of rescue analgesia at 24 hours were evaluated. RESULTS: VASr and VASa were significantly higher in group S in comparison to other groups (P < 0.05). Duration of analgesia was significantly longer in Group T and Group M than in Group S (P < 0.05). The difference between group T and group M was also significant (P < 0.05). Number of rescue analgesia and total analgesic consumption at postoperative hour 24 was significantly fewer in group M compared with other groups (P < 0.05). CONCLUSIONS: Intra-articular levobupivacaine-tenoxicam-morphine combination provides effective pain relief, longer analgesic duration, and less analgesic requirement when compared with intra-articular levobupivacaine-tenoxicam-tramadol combination and saline after knee arthroscopic surgery.

Comparison of unilateral spinal and continous spinal anesthesia for hip surgery in elderly patients.

BACKGROUND: Continous spinal anesthesia (CSA) and frequently unilateral spinal anesthesia (USpA) are usually preferred for lower extremity surgeries. In this study, we aimed to compare the effects of these anesthetic techniques, on hemodynamic parameters, quality of anesthesia and complications in elderly patients undergoing hip surgeries. METHODS: Forty patients aged 65 years and older, assigned to receive either CSA or USpA with 7.5 mg (1.5 cc) 0.5% hyperbaric bupivacaine initially. In CSA group, additional doses of 2.5 mg bupivacaine were applied until sensory block reach to T10. Maximum sensorial block level, time to reach the level of T10 (defined as onset time) and to regress to T12, hemodynamic parameters and ephedrine requirements were recorded peroperatively and during 2 h postoperatively. RESULTS: Hemodynamic parameters, ephedrine requirements and regression of sensory block by two levels were similar in two groups. The onset time of anesthesia was significantly longer in USpA group than CSA group. Neuraxial anesthesia had to be converted to general anesthesia in 5 patients (25%) in CSA group and 1 patient (5%) in USpA group. CONCLUSIONS: We conclude that both USpA and CSA techniques have similar effects in elderly high risk patients. On the other hand, USpA is more preferable for surgeries with shorter durations due to its low cost and high success rate.

Cesarean section under spinal anesthesia in a patient with ankylosing spondylitis--a case report.

INTRODUCTION: It is generally accepted that neuraxial anesthesia is difficult to establish in patients with ankylosing spondylitis. 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. CASE: 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. CONCLUSION: We suggest that spinal anesthesia can be safely and effectively used as an alternative to general anesthesia in patients with ankylosing spondylitis. Neuraxial techniques should not be regarded as unachievable in such patients; however, all necessary precautions should be taken to avoid complications of spinal anesthesia, and facilities to secure the airway should be available.
