    ABSTRACT: Objective: To investigate the risk factors for postoperative arytenoid dislocation. Methods: From September 2003 to August 2013, the records of 16 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in terms of date and type of procedures were chosen as the controls (n=16). Recorded data for all patients were demographics, smoking status, alcoholic status, preoperative physical status, airway evaluation, intubation procedures, preoperative laboratory test results, anesthetic consumption and intensive care unit stay. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocation, and the outcomes of surgical repair and conservative treatment. Categorical variables were presented as frequencies and percentages, and were compared using the chi-squared test. Continuous variables were expressed as means±SD and compared using the Student's unpaired t-test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis. Results: Sixteen patients with postoperative arytenoid dislocation were enrolled, with a median age of 52 years. Most postoperative arytenoid dislocation patients (15/16, 93.75%) received surgical repair, except one patient who recovered after conservative treatment. None of the postoperative arytenoid dislocation patients were smokers. Red blood cell (P=0.044) and hemoglobin (P=0.031) levels were significantly lower among arytenoid dislocation cases compared with the controls. Conclusions: Non-smoking and anemic patients may be susceptible to postoperative arytenoid dislocation. However, neither of them was independent risk factor for postoperative arytenoid dislocation.

    ABSTRACT: Ketamine is hypothesized to reduce perioperative endocrine-metabolic and inflammatory responses in cardiac surgery patients. This randomized, placebo-controlled, double-blind study was performed to determine whether perioperative endocrine-metabolic and inflammatory responses are attenuated by preoperative administration of ketamine to healthy females receiving elective laparoscopic surgery. Forty female patients with American Society of Anesthesiologist classification I or II who elected to receive gynecological laparoscopic surgery were randomly assigned to the ketamine-treated (group K; n = 20) or control (group C; n = 20) group. At 2 minutes prior to induction patients in group K received ketamine (0.25 mg/kg) whereas those in group C received normal saline. All patients received standardized general anesthesia. Serum glucose and cortisol values were measured before ketamine administration (T0), 2 minutes after tracheal intubation (T1), 30 minutes after skin incision (T2), 2 minutes after tracheal extubation (T3) and 1 hour postoperatively (T4). Serum interleukin-6 and tumor necrosis factor-α values were determined at T0 and T4. Postoperative analgesic efficacy, side effects of administered drugs, and time to discharge were recorded. Compared with subjects in group C, those in group K had lower serum glucose values at T1, T2, T3 and T4 and lower serum cortisol values at T4 (P < 0.05). Postoperative interleukin-6 and tumor necrosis factor-α concentrations for group K were lower than those for group C (P < 0.05). Postoperative visual analog scale scores at rest, cumulative fentanyl consumption, and time to discharge were lower in group K as compared to group C (P < 0.05). No significant differences in drug side effects were observed postoperatively between the two groups. Endocrine-metabolic and inflammatory responses to laparoscopic surgery are attenuated in part by pre-incisional administration of ketamine.

    ABSTRACT: The excess fatty tissues on the head, neck, thorax, and abdomen of morbid obese patients can impede the patency of the upper airway and impair lung functions. Meanwhile, these patients often have comorbidities such as obstructive sleep apnea, hypoventilation syndrome, chronic obstructive pulmonary disease, and asthma, which may result in difficult airway, intraoperative hypoventilation, and postoperative respiratory depression. Therefore, perioperative airway management for morbid obese patients may pose a big challenge to anesthesiologists. Anesthesiologists should know well about the pathophysiological features of respiratory system and grasp rational management principles, so as to improve the safety and effectiveness of perioperative airway management and optimize the clinical prognosis.

    ABSTRACT: The purpose of this study was to establish the streptozotocin (STZ)-induced diabetic model with rats and investigate the antinociceptive effect of combination of Tramadol (TR) and Acetaminophen (NAPA) on the animal model for the first time. Diabetic model was induced by a single injection of STZ (60 mg/kg, intraperitoneal). Nociceptive thresholds were measured by means of electronic von Frey test, hot-plate test, and tail-flick test. On the 28th day of diabetes induction, diabetic rats with significant hyperalgesia were randomly divided into three groups: TR, NAPA, and TR-NAPA combination group. Each group was randomly divided into four subgroups. Three geometric series of drugs were given to each group respectively. Antinociceptive effects of the drugs were assessed at 15, 30, 60, 120, and 180 minutes after drug administration. 50% Maximum antinociceptive effect of each drug was determined by probit analysis, whereas interaction between TR and NAPA was evaluated by isobolographic analysis. Hyperalgesia, along with hyperglycemia, developed 4 days after STZ injection and persisted at all tested time points until 28 days. TR, NAPA, and TR-NAPA combination administration all produced dose-dependent antinociceptive effects. Isobolographic analysis showed a significant deviation of TR/NAPA 50% maximum antinociceptive effect (in tail-flick test, but not in von Frey test) from the additive line. Combination of the two drugs produces an additive antinociceptive effect in tail-flick test, whereas probable additive antinociceptive effect in von Frey test in painful diabetic neuropathy rats.

    ABSTRACT: To investigate the expression changes of metabotropic glutamate receptor 5 (mGluR5) in neuropathic pain. Eighty-four adult male Sprague Dawley rats weighing 180-220 g were randomly divided into 7 groups (n = 12) : control group; S3, S7, and S14 groups: rats received the sham operation, the mechanical pain threshold was measured, and then the rats were decapitated and the ipsilateral lumbar spinal cord dorsal horn and dorsal root ganglion (DRG) samples were obtained on the 3rd, 7th, 14th postoperative day, respectively; C3, C7, and C14 groups: the chronic sciatic nerve constriction (CCI) model was established, the mechanical pain threshold was measured and the samples were obtained on the 3rd, 7th, 14th postoperative day, respectively. The expression level of mGluR5 mRNA and protein in the spinal cord and DRG were measured using the reverse transcriptase polymerase chain reaction and Western blot. In the CCI group, the mechanical pain threshold in each observation day was significantly lower than in the sham operation group (P < 0.05). In the spinal cord, the expressions of mGluR5 mRNA and protein were significantly elevated in the C3 group than in the S3 and the control group (P < 0.05). On the 7th and the 14th postoperative day, no significant difference was found in the expression of mGluR5 mRNA and protein between CCI groups and the sham operation groups or the control group. No change was detected in DRG mRNA or protein. mGluR5 is differentially expressed in spinal cord in response to neuropathic pain, which suggests that mGluR5 may be involved in the mechanism of neuropathic pain.

    ABSTRACT: To investigate the anesthetic management features of laparoscopic adrenalectomy for pheochromocytoma. Twelve patients scheduled for laparoscopic adrenalectomy for pheochromocytoma under general anesthesia were allocated into group 1, while another 12 patients who received transabdominal adrenalectomy for pheochromocytoma under general anesthesia were selected as group 2. The hemodynamic changes and the postoperative recovery profiles between the two groups were compared. Hemodynamic fluctuation occurred during carbon dioxide insufflation and tumor manipulation in group 1. However, there were no differences between the two groups. Duration of post operative recovery and hospital stay as well as requirement of analgesics in group 1 were significantly lower than those in group 2 (P < 0.05). Hemodynamic fluctuation still exists during laparoscopic adrenalectomy for pheochromacytoma. However, patients undergoing such surgical procedure recover faster as compared with open surgery.

    ABSTRACT: To analyze tracheal intubation and respiratory treatment in the critical severe acute respiratory syndrome (SARS) patients. Review and analyze tracheal intubation and respiratory treatment in critical SARS patients in intensive care unit (ICU). Three of thirteen patients had been intubated or received tracheotomy before they entered into ICU, the other patients received treatment of nasal cannula or oxygen mask. With the development of the disease, two patients had been intubated because of respiratory failure or tracheotomy. Tracheal intubation was twice made in two patients in order to replace tracheal tubes. The patient should be intubated or received tracheotomy if non-invasive respiratory support has no effect. Standard protection could protect medical staff from infection under tracheal intubation.
