目的:比较心肺复苏机与徒手心肺复苏抢救心脏骤停患者的临床疗效,寻求有效的心脏骤停的抢救方法。方法回顾性分析100例心脏骤停患者临床资料。2011年1月至2012年1月收治的50例心脏骤停患者作为对照组,采取徒手心肺复苏进行抢救;2012年1月至2013年1月收治的50例心脏骤停患者作为观察组,采取心肺复苏机进行抢救。观察并比较两组患者术后的疗效。结果观察组心肺复苏后收缩压、SpO2及心率分别为(95.2±10.4) mmHg、(93.1±8.2)%、(89.6±5.7)次/min,均明显高于对照组的(71.8±6.7)mmHg、(78.7±5.5)%、(70.8±5.2)次/min,组间差异有统计学意义(t=8.456、8.246、9.625,均P<0.05);两组呼吸频率差异无统计学意义(t=0.955,P>0.05);观察组复苏成功率及存活率分别为72%、46%,均明显高于对照组(44%、22%),观察组不良反应发生率为2%,低于对照组(18%),组间差异均有统计学意义(χ2=8.05、6.42、10.15,均P<0.05)。心肺复苏后5 min两组患者动脉血气分析指标PaO2、PaCO2、SaO2差异均无统计学意义( t=0.868、0.922、0.747,均P>0.05);15 min、30 min后两组患者PaO2、PaCO2、SaO2等动脉血气分析指标差异均有统计学意义( t=5.984、4.673、4.685、9.647、8.356、5.534,均P<0.05)。结论心肺复苏机较徒手心肺复苏在抢救心脏骤停患者中具有明显优势,可明显缩短自主循环时间,提高心肺复苏成功率,疗效确切,且不良反应较少,是一种简单、安全和有效的抢救方法,值得在临床广泛推广应用。 相似文献

Pralidoxime is a common antidote for organophosphate poisoning; however, studies have also reported pralidoxime's pressor effect, which may facilitate the restoration of spontaneous circulation (ROSC) after cardiac arrest by improving coronary perfusion pressure (CPP). We investigated the immediate cardiovascular effects of pralidoxime in anaesthetised normal rats and the effects of pralidoxime administration during cardiopulmonary resuscitation (CPR) in a pig model of cardiac arrest. To evaluate the immediate cardiovascular effects of pralidoxime, seven anaesthetised normal rats received saline or pralidoxime (20 mg/kg) in a randomised crossover design, and the responses were determined using the conductance catheter technique. To evaluate the effects of pralidoxime administration during CPR, 22 pigs randomly received either 80 mg/kg of pralidoxime or an equivalent volume of saline during CPR. In the rats, pralidoxime significantly increased arterial pressure than saline (P = .044). The peak effect on arterial pressure was observed in the first minute. In a pig model of cardiac arrest, CPP during CPR was higher in the pralidoxime group than in the control group (P = .002). ROSC was attained in three animals (27.3%) in the control group and nine animals (81.8%) in the pralidoxime group (P = .010). Three animals (27.3%) in the control group and eight animals (72.2%) in the pralidoxime group survived the 6-hour period (P = .033). In conclusion, pralidoxime had a rapid onset of pressor effect. Pralidoxime administered during CPR led to significantly higher rates of ROSC and 6-hour survival by improving CPP in a pig model. 相似文献

心内膜临时心脏起搏在心跳骤停复苏抢救中的临床研究 总被引:1,自引:0,他引:1
目的:了解心内膜临时心脏起搏对心跳骤停抢救时应用的方法及疗效,探索提高心跳骤停抢救的成功率。方法:通过经左锁骨下静脉或右股静脉穿刺置入电极导管,在起搏心电图或电极孚管激惹室性早搏引导下,定位电极,紧急临时心脏起搏,抢救心脏停搏患者,统计复苏成功率。结果:试验组中,1例是创伤引起的心跳骤停、起搏成功;其余17例是随机选取心跳骤停的患者,其中1例起搏有效。结果该组心跳骤停的抢救心跳恢复7例;心跳复跳成功率为38.8%。研究结果显示本方法对非室颤性心脏停搏的患者心内膜起搏配合心肺复苏可取得较好的效果。结论:在心跳骤停患者抢救中使用心脏起搏术对复苏成功率并没有明显的提高,如何判断采用临时起搏器的时机和看待其意义应该得到临床工作者的重视。 相似文献

The assessment and treatment of patients requiring cardiopulmonary resuscitation (CPR) is discussed. Cardiovascular pharmacotherapy is discussed as suppressive therapy, stimulant therapy and treatment of hypotension. Special situations covered include hyperkalemia, anaphylaxis and drug overdosages. It is concluded that the likelihood of success of CPR depends on the rapid initiation of ventilation and restoration of circulation, and is inversely dependent on the severity of the underlying disease or injury. 相似文献

The Brighton resuscitation ambulances: review of 40 consecutive survivors of out-of-hospital cardiac arrest 总被引:3,自引:0,他引:3
A F Mackintoch M E Crabb R Granger J H Williams D A Chamberlain 《British medical journal》1978,1(6120):1115-1118
In three years 40 patients were resuscitated by ambulancemen after out-of-hospital cardiac arrest and survived to be discharged. Twenty-six of these had had circulatory arrest before an ambulance arrived and a further three had developed ventricular fibrillation before they were moved. Thirty-two patients were alive at the time of review six months to three and a half years later. Resuscitation by ambulancemen can be effective for patients with unheralded sudden cardiac arrest as well as for patients with recent myocardial infarction. Survivors of out-of-hospital ventricular fibrillation may have a favourable long-term prognosis. 相似文献

Endotracheal drug therapy in cardiopulmonary resuscitation 总被引:1,自引:0,他引:1
C L Raehl 《Clinical pharmacy》1986,5(7):572-579
Use of endotracheal drug therapy during cardiopulmonary resuscitation (CPR) is reviewed. Endotracheal drug therapy--instillation of a drug solution directly into an endotracheal tube for absorption into the circulation via the alveoli--may be used during CPR when venous access is limited. Administration of drugs via a central vein is the most efficient route, but a central i.v. line may not be present and peripheral venous administration may not be possible because of vasoconstriction, trauma, other patient-related factors, or absence of personnel trained to insert i.v. catheters. An endotracheal tube is usually inserted during CPR; in most cases, this procedure can be performed outside the hospital by emergency medical personnel. Basic life-support measures are not interrupted during endotracheal administration as they are in intracardiac drug administration. Drugs that may be administered by the endotracheal route include epinephrine, atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate. Endotracheal delivery of calcium salts, sodium bicarbonate, and bretylium tosylate is not recommended. Pharmacokinetic data for drugs administered endotracheally are lacking; therefore, dosage recommendations are empirical. Usually, the same dose is administered endotracheally as by the i.v. route. Little is known about choice and volume of diluent and the best anatomic site of application. Endotracheal drug administration may replace intracardiac injection as the second-line alternative to intravenous drug injection during CPR. 相似文献
