With the popularization of cardiopulmonary resuscitation (CPR) technology, the success rate of restoration of spontaneous circulation (ROSC) is gradually improved, and the survival rate and neurological outcome of patients with cardiac arrest are improved. Currently, therapeutic methods for cerebral resuscitation after cardiac arrest are limited. In addition to mild hypothermia for clinical application, the majority of drugs remain in the animal experimental stage. Finding effective brain protection drugs has become a hot spot in the field of brain resuscitation research. This article will review the pharmaceutical progress of research for cerebral resuscitation after cardiac arrest, so that we can study the brain protection mechanism of these drugs better and more targeted.

OBJECTIVE: To assess the effects of Shenfu Injection (, SFI) on blood lactate, and secondarily its effect on the lactate clearance (LC) in patients with post cardiac arrest syndrome (PCAS). METHODS: The present study is a post hoc study of a randomized, assessor-blinded, controlled trial. Patients experienced in-hospital cardiac arrest between 2012 and 2015 were included in the predefined post hoc analyses. Of 1,022 patients enrolled, a total of 978 patients were allocated to the control group (486 cases) and SFI (492 cases) group, receiving standardized post-resuscitation care bundle (PRCB) treatment or PRCB combined with SFI (100 mL/d), respectively. Patients' serum lactate was measured simultaneously with artery blood gas, lactate clearance (LC) was calculated on days 1, 3, and 7 after admission and compared between groups. Lactate and LC were also compared between the survivors and non-survivors according to the 28-d mortality, as well as the survivors and non-survivors subgroups both in the SFI and control groups. RESULTS: In both groups, compared with pre-treatment levels, mean arterial pressure (MAP) and PaO₂ were significantly improved on 1, 3, 7 d after treatment (P<0.05), while heart rate (HR) and blood glucose levels were significantly decreased on 1, 3 and 7 d after treatment (P<0.05). compared with control group, SFI treatment improved the values of MAP and PaO₂ (P<0.05), and significantly decreased the levels of HR and the blood glucose level on 3 and 7 d after treatment (P<0.05). Compared with the control group, lactate levels decreased faster in the SFI group versus the control group on 3 and 7 d (P<0.05). From initiation of treatment and the following 3 and 7 d, SFI treatment greatly increased the LC compared with that in the control group (P<0.05). Compared with survivors, non-survivors had higher admission lactate levels (7.3 ±1.1 mmol/L vs. 5.5 ±2.3 mmol/L; P<0.01), higher lactate levels on days 1, 3 and 7 (P<0.05), and LC were decreased significantly on 3 and 7 d after treatment (P<0.05). Similar results were also found both in the SFI and control groups between survivors and non-survivors subgroups. CONCLUSION SFI in combination with PRCB treatment is effective at lowering lactate level and resulted in increasing LC in a targeted population of PCAS patients.

Cardiac arrest is the most serious complication during anesthesia and surgery. Once cardiac arrest is diagnosed, whether the heart is in standstill or in ventricullar fibrillation and whatever is the initial cause, the immediate treatment must be aimed at providing an artificial circulation of oxygenated blood to the vital organs. Authors have experienced cardiac arrest due to ventricular fibrillation during general anesthesia with hypotensive technique. When the diagnosis was established, immediate closed chest cardiac massage was carried out with drug therapy and D.C. defibrillator. Cardiac rhythm was restored immediately after the 100 joules of electric shock was given. The duration of closed chest cardiac massage was 18 minutes. The patient recovered completely without complications.

It is a well known fact that cardiac arrest can occur during general or regional anesthesia. When cardiac arrest occurs, immediate measures to resuscitate and diagnose, whether for ventricular fibrilIation or cardiac standstill, should be taken to save the patients life and to prevent permanent damage to the central nervous system. The authors had experienced of a cirdiac arrest due to ventricular fibrillation during local infiltration anesthesia with xylocaine and epinephrine for tonsillectomy. As soon as the diagnosis of ventricular fibrillation was made by EKG, while the oxygenation and closed cardiac massage were performed, the external D.C. defibrillation was carried out and drug therapy was given. The cardiac rhythm, was ventricular tachyeardia at first, then sinus rhythm was restored after the defibrillation. The patient recovered completely without any complications and was discharged from the hospital two days later.

Survival rates after cardiac arrest have not changed substantially over the past 5 decades. Postcardiac arrest (CA) syndrome (PCAS) is the primary reason for the high mortality rate after successful restoration of spontaneous circulation (ROSC). Intravenous administration of Shenfu Injection (, SFI) may attenuate post-CA myocardial dysfunction and cerebral injury, inhibit systemic ischemia/reperfusion responses, and treat underlying diseases. In this article, we reviewed the therapeutic effects of SFI in PCAS. SFI might be useful in the treatment of PCAS, incorporating the multi-link and multi-target advantages of Chinese medicine into PCAS management. Further experimental and clinical research to verify the therapeutic effects of SFI in PCAS is required.

Candidiasis is the most common fungal infection complicating the course of patients with hematologic malignant neoplasms. Although widespread organ involvement is characteristic of disseminated candidiasis, reports of skin are rare. Reports describing typical clinical and histopathological finding of cutaneous lesions are very important since it may enable a diagnosis of disseminated candidiasis to be made and thus antifungal therapy can be initiated earlier. A 50-year-old housewife was admitted with a 5-month history of fatigue and easy bruising. She was diagnosed as ha.ving acute myelocytic leukemia and treatment was begun with daunorubicin and cytosin, arabinoside. Eight days after the start of chemotherapy, she developed a fever and generalized tender well demacated erythematous to purplish papulonodular eruption. A biopsy specimen from the skin lesion showed perivascular mononuclear cell infiltration and spore and pseudohypae v,rere found within the dermis and subcutis in PAS stain. Cultures of one skin biopsy specimen and one of four blood sarnples grew Candida tropicalis. The patient was treated with intravenous amphotericin B for disseminated candidiasis. On the tenth day of antifun gal therapy, she developed cardiopulmonary arrest and died.

BACKGROUNDEpinephrine has been used as a first-choice vasopressor drug for cardiac arrest (CA) since 1974. However, the administration of epinephrine is controversial. This study aims to compare the effects of Shen-Fu injection (SFI) and epinephrine on resuscitation outcomes in a porcine model of prolonged CA.

METHODSVentricular fibrillation (VF) was electrically induced. After 8 minutes of untreated VF and 2 minutes of chest compressions, 24 pigs were randomly divided into 3 groups (n = 8 per group): central venous injection of SFI (SFI group), epinephrine (EPI group), or saline solution (SA group). The haemodynamic status and oxygen metabolism parameters, including cardiac output, mean arterial pressure, left ventricular dp/dtmax and negative dp/dtmax, oxygen delivery (DO2), and oxygen consumption (VO2), were calculated.

RESULTSSFI shortened the time to restoration of spontaneous circulation (ROSC) and decreased the number of shocks, similar to epinephrine. However, the mean arterial pressure, cardiac output, left ventricular dp/dtmax and negative dp/dtmax were significantly higher in the SFI group than in the EPI group at 4 and 6 hours after ROSC. VO2 and ERO2 decreased after ROSC and then increased. VO2 and ERO2 were significantly higher in the SFI group than in the EPI and SA groups after ROSC, while those were lowest in the EPI group among all groups.

CONCLUSIONSSFI shortened the time to ROSC and decreased the number of shocks, similar to epinephrine. However, SFI improved oxygen metabolism, and produced a better hemodynamic status compared with epinephrine. SFI might be a potentially vasopressor drug for the treatment of CA.

OBJECTIVETo compare the effects of Shenfu Injection (SFI) and epinephrine (EPI) on catecholamine levels in a porcine model of prolonged cardiac arrest (CA).

METHODSAfter 8 min of untreated ventricular fibrillation, 24 Wuzhishan miniature pigs were randomly assigned to one of the three groups (n=8 per group) and received central venous injection, respectively: SFI group (1 mL/kg), EPI group (20 μg/kg EPI), and normal saline (NS) group. Cardiac output (CO), maximum rate of increase/decrease in left ventricular pressure (±dp/dt), serum levels of EPI, norepinephrine (NE), and dopamine (DA) were determined at baseline and at 0.5, 1, 2, and 4 h after restoration of spontaneous circulation.

RESULTSThe duration of cardiopulmonary resuscitation was shorter in the EPI and SFI groups than in the NS group (P<0.05). The EPI level increased significantly after restoration of spontaneous circulation (ROSC) in all three groups, and was significantly different between the EPI group and the other two groups immediately after ROSC (both P<0.01), but these differences gradually disappeared over time. There were no significant differences in NE or DA levels among the three groups, and there were no correlations between catecholamine levels and CO or dp/dt (P>0.05).

CONCLUSIONSSFI did not significantly affect endogenous catecholamine levels during cardiopulmonary resuscitation after prolonged ventricular fibrillation. However, SFI improved oxygen metabolism, and produced a better hemodynamic status compared with EPI. SFI might be a potentially vasopressor drug for the treatment of CA.

OBJECTIVETo investigate the effects of Shenfu Injection (, SFI) on cerebral metabolism in a porcine model of cardiac arrest (CA).

METHODSThirty Wuzhishan minipigs were randomly assigned to the control group (n=6), epinephrine group (EP group, n=12) and Sfigroup (n=12). After 8 min of untreated ventricular fifibrillation (VF), pigs in the EP group or Sfigroup were administered with either EP (0.02 mg/kg) or Sfi(1.0 mL/kg), respectively. After successful resuscitation, cerebrospinal fluid (CSF) levels of glucose, pyruvate, lactate, glutamate and glycerol were measured at 1, 6, 12 and 24 h after recover from spontaneous circulation (ROSC). In addition, neurologic defificit score (NDS) was calculated at 24 h after ROSC. Surviving pigs were killed at 24 h after ROSC, and the brain tissue was obtained for ultra-microstructure examination.

RESULTSCompared with the EP group, CSF glucose and pyruvate levels were higher (all P<0.01), and lactate levels were lower in the Sfigroup (P<0.01). Meanwhile, CSF glutamate and glycerol levels in the Sfigroup were lower in comparison to the EP group (all P<0.05). In addition, Sfidecreased NDS at 24 h after ROSC (P<0.01), and alleviated the histopathological damage of the brain.

CONCLUSIONSSficould alleviate brain injury after CA, which may be associated with improving cerebral metabolism.
