Objective To investigate the effects of ketamine combined with moderate hypothermia on brain ischemia-reperfusion (I/R) injury in a rat model of asphyxial cardiac arrest. Methods Fifty healthy Wistar rats of both sexes aged 4.0-4.5 months, weighing 410-510 g were randomly allocated into 5 groups (n = 10each): group Ⅰ sham operation (group S), group Ⅱ asphyxial cardiac arrest (group ACA), group Ⅲ ketamine (group K), group Ⅳ moderate hypothermia (group MH) and group Ⅴ K + MH. The animals were anesthetized with intraperitoneal (IP) phenobarbital 20 mg/100 g, tracheostomized and mechanically ventilated (RR 60 bpm,FiO2 50%), PaCO2 was maintained at 35-45 mm Hg. Cardiac arrest was induced by clamping tracheal tube until ECG activity disappeared and MAP < 15 mm Hg. Resuscitated was started 5 min later. MAP > 60 mm Hg and HR > 250 bpm were considered to be signs of successful resuscitation. Dead animals and animals in which resuscitation time was longer than 5 min were excluded from the study. In group K ketamine 100 mg/kg was administered IP at 5 min before asphyxia. In group MH hypothermia was started as soon as asphyxia was started and body temperature was maintained at 30-35 ℃. After successful resuscitation, the animals were sacrificed. Their brains were removed for determination of brain water content and p-caspase-3 expression in hippocampus. Results Brain I/Rsignificantly increased brain water content and p-caspase-3 expression in group ACA. MH alone significantly attenuated 1/R-induced brain edema and decreased p-caspase-3 expression, while ketamine alone only significantly decreased p-caspase-3 expression but did not decrease I/R-induced brain edema. MH + K decreased p-caspase-3expression further but did not reduce brain edema further as compared with MH alone. Conclusion Ketamine combined with moderate hypothermia provides better protection against brain I/R injury.

Objective:To observe the rate of skin injury after spinal cord injury (SCI) in the rehabilitation department and analyze its risk factors.Methods:A total of 120 SCI patients were divided into an injury group of 33 and a control group of 87 without injury. The occurrence, type and location of any skin injuries incurred during hospitalization were recorded along with the subjects′ general condition, injury and functional status, complications, and the rehabilitation and nursing measures applied. Multivariate logistic regressions were evaluated to identify the risk factors for skin injury.Results:Among the 33 injuries, 27 were bruises (58.7%), 10 were stress injuries (21.7%), 5 were lacerations (10.9%) and 4 were burns (8.7%). Most injuries (65.2%) were to the limbs, followed by the buttocks and the sacrococcygeal tail (34.8%). All of the skin injuries required nursing intervention, with 47.8% lasting more than 7 days. There were significant differences between the two groups in terms of their average hospital stay, dysfunction, mode of admission, risk of pressure injury, nutrition and assisted urination. The regressions identified significant relationships between the occurrence of skin injury and length of hospital stay, risk of pressure injury and nutrition.Conclusions:The incidence of skin injury is high among hospitalized SCI patients. A long hospital stay, pressure injury and poor nutrition are independent risk factors for such patients. Such patients should receive skin management education.
