Severe tracheal stenosis can not only cause critical medical problems such as severe shortness of breath, hypoxia, and even orthopnea, but also impose overwhelming challenges on the physicians, particularly the anesthesiologist. Life-threatening airway obstruction can make the patient's gas exchange extremely difficult.Though several options could be offered regarding the treatment of tracheal stenosis, normally, tracheal resection and following reconstruction is the first choice for severe airway stenosis. Successful surgical intervention relies on the close communication and cooperation between surgeons and anesthesiologists. In these cases, airway management is the top issue for the anesthesiologist, and the level of difficulty varies with stenosis location, severity of stenosis, and surgical technique. Extracorporeal membrane oxygenation (ECMO), or cardiopulmonary bypass (CPB), is rarely utilized for the surgery, but for those impossible airways due to nearly complete tracheal obstruction, ECMO or CPB could be the final choice for anesthesiologists. Here we report a case of successful urgent airway management for tracheal resection and reconstruction assisted by temporary CPB.

OBJECTIVETo investigate the expression profile of interleuki-1β (IL-1β) in rat myocardium at different time points during hypoxia/reoxygenation(H/R)transition.

METHODSThe isolated Langendorff perfused rat heart model was established.Forty SD rats were randomly divided into sham group (A group) and hypoxia/reoxygenation group (H/R group). The H/R group rats were subdivided into H/R 0.5 h group(B group), H/R 1 h group(C group), H/R 2 h group(D group)according to reoxygenation time. The left ventricular development pressure(LVDP), maximal rates of increase/decrease of the left ventricular pressure(±dp/dtmax) were continuously recorded. The concentration of interleukin-1β(IL-lβ) and creatine kinase-MB (CK-MB) in myocardium was measured by ELISA. The mRNA expression of IL-lβ in myocardium was determined by RT-PCR. Microstructure of myocardium was observed under light microscopy.

RESULTSThe value of LVDP and ±dp/dtmax in hypoxia/reoxygenation group rat were significantly lower than that in sham group(P < 0.05). The expression of IL-lβ and CK-MB at protein level and the expression of IL-1β at mRNA level in hypoxia /reoxygenation group were higher than that in sham group(P < 0. 05). There were significant differences of the above parameters among H/R 0.5 h, 1 h, 2 h group(P <0.05). The concentration of IL-1β and CK-MB, the mRNA expression of IL-1β were higher in H/R 2 h group than that of other groups(P < 0.05).

CONCLUSIONThe high expression of IL-Iβ in myocardium after myocardial hypoxia /reoxygenation in rats might lead to. ischemia/reperfusion injury.

Objective:To observe the motor capacity of patients early after cardiac surgery using a cardiopulmonary exercise test.Methods:Patients who had performed a cardiopulmonary exercise test within 3 months after cardiac surgery were included in this retrospective study. Patients who took the test within 30 days of the operation formed a discharge group ( n=20), those within 30 to 60 days and 60 to 90 days formed the one month and two month groups ( n=10 for both). The discharge group was further divided into an aortic surgery group ( n=9), a bypass surgery group ( n=6) and a valve surgery group ( n=5) according to their procedure. The exercise capacity of each person was measured in terms of the changes in heart rate and systolic pressure from the resting to the anaerobic threshold stage. Anaerobic threshold, peak oxygen uptake and carbon dioxide ventilation equivalent were also recorded. Results:All of the patients completed the cardiopulmonary exercise test above the anaerobic threshold, and no adverse events such as exercise accidents occurred. At the anaerobic threshold the average heart rate of the discharge group was (8.8±7.1)bpm, significantly lower than the averages of the one month and two months groups: (17.0±5.9) and (18.3±10.5)bpm respectively. The average anaerobic thresholds and peak oxygen uptakes of the 1 month and 2 months groups were not significantly different, but they were all significantly higher than the discharge group′s averages. There were, however, no significant differences among the groups in the average changes in their systolic pressure and carbon dioxide ventilation equivalent. Moreover, the average anaerobic threshold and peak oxygen uptake of the aortic surgery group and the bypass surgery group were significantly lower than the valve surgery group′s averages.Conclusions:Postoperative motor ability after cardiac surgery improves significantly for at least 30 days. Patients who have received aortic or bypass surgery have significantly lower exercise capacity than those after valve surgery.

OBJECTIVETo investigate the mandibular bone mineral density (BMD) change of senile osteoporosis patients and the relationship between the mandible bone loss and systemic bone loss.

METHODSForty senile osteoporotic patients (group A), 40 non-osteoporosis control elders (group B) and 40 healthy youths (group C) were included in this study. Standard digital panoramic tomography (SDPTG) was taken for each participant. Cortical width (CW), panoramic mandibular index (PMI), alveolar bone density and alveolar bone height were measured on the SDPTG. Lumbar and hip BMD were measured with dual energy X-ray absorptiometry (DXA).

RESULTSClose relationship was found between CW (3.57 +/- 0.82) and systemic BMD for osteoporosis patients (P < 0.05). All the SDPTG indices including CW, PMI, alveolar bone density and alveolar bone height were different for osteoporosis patients from the healthy youths (P < 0.05). The osteoporosis patients had thinner CW (3.57 +/- 0.82) and smaller PMI (0.29 +/- 0.06) than non-osteoporosis control elders (CW: 4.07 +/- 0.75, PMI: 0.32 +/- 0.07, P < 0.05). The alveolar bone density (105.40 +/- 20.48) and alveolar bone height (10.42 +/- 1.82) of the non-osteoporosis control elders reduced compared with the healthy youths (alveolar bone density: 117.10 +/- 22.23, alveolar bone height: 11.69 +/- 1.63, P < 0.05).

CONCLUSIONSThe senile osteoporotic patients had significant mandibular cortical bone loss.

OBJECTIVETo evaluate the clinical efficacy of domestic sevoflurane by comparing the pharmacokinetic and pharmacodynamic characteristics of domestic sevoflurane and an imported product.

METHODSEighty patients undergoing general anesthesia for transabdominal hysterectomy were equally randomized into domestic sevoflurane group and imported sevoflurane group. The following data were recorded and compared: vital signs; change of sevoflurane concentrations in the induction period and recovery period; the time when inhaled sevoflurane concentration reached half of the pre-set concentration of the vaporizer; the time when the end-tidal sevoflurane concentration reached half of the pre-set concentration of the vaporizer; the time when the end-tidal sevoflurane concentration reached half of inhaled sevoflurane concentration; the time of the end-tidal sevoflurane concentration reached 0. 8 MAC in the induction period; the recovery time; the extubation time; and time to recovery of consciousness.

RESULTSThe general conditions of the two groups were not significantly different. The pharmacokinetic and pharmacodynamic parameters at the intra-operative time points as well as the minimal alveolar concentration, the inspired and end-tidal sevoflurane concentrations, and the time to recovery of consciousness also showed no significant differences between the two groups.

CONCLUSIONThe domestic sevoflurane has similar pharmacokinetic and pharmacodynamic characteristics as the imported products. It can serve as a cost-effective product for transabdominal hysterectomy.
