ABSTRACT
【Objective】 To explore the perioperative blood management in patients with pancreatic pseudocyst combiend with coagulation factor Ⅴ(FⅤ) deficiency. 【Methods】 Preoperative: In order to determine the effect of cryoprecipitated antihemophilic factor and fresh frozen plasma (FFP) on the elevation level of factor Ⅴ, we alternately infused cryoprecipitate and FFP in the resting state. TEG, coagulation function and coagulation factor activity were monitored before and 1 h, 24 h and 48 h after infusion, and intraoperative and postoperative blood transfusion strategies were formulated. FFP 600 mL and cryoprecipitate 10 U were supplemented preoperatively. Intraoperative: The operation procedure was performed for 7 hours with an infusion of 600 mL FFP without significant bleeding. Postoperative: FFP was infused. 【Results】 Preoperative: The coagulation factor Ⅴ activity on pre-operation was 1.9% and 1.8%. After alternating infusion cryoprecipitate 10 U and FFP 1 200 mL, the FⅤactivity increased to 5.1% and 6.0%, respectively. There was no significant difference in TEG parameters, PT and ATPP results were decreased to varying degrees. Intraoperative: The operation was successful without obvious bleeding. Postoperative: FFP 500 mL was infused 2 h after operation, and FFP 250-500 mL was injected daily from 1 to 7 days after surgery. No significant bleeding was observed in the wound, the results of TEG, PT, APTT and hemoglobin (Hb) did not change significantly compared with those before surgery. The patient was discharged successfully 12 days after surgery. The genetic test results showed that he had inherited coagulation factor Ⅴ deficiency, which was a compound heterozygous variation. 【Conclusion】 Perioperative blood management in patients with FⅤ deficiency combined with surgical disease, requiring pre-transfusion evaluation and post-transfusion evaluation in combination with laboratory investigations and clinical manifestations, cryoprecipitate and fresh frozen plasma can be effective in supplementing coagulation factors. The TEG seems to be better than the Seven items of coagulation function in judging the clotting status of patients with FⅤ deficiency.
ABSTRACT
【Objective】 To explore the effect of allogeneic platelet gel on hemostasis and repair of vascular anastomoses and wounds in patients with giant aortic aneurysms during surgery. 【Methods】 One adult dose of allogeneic platelets, applied as platelet rich plasma (PRP), was prepared as platelet gel (PG) (about 220 mL) for spraying or smearing at the vascular anastomosis and thoracic wound during the surgery of giant aortic aneurysms. 【Results】 The gel formation was presented about 30 seconds after spraying or smearing with PG on the anastomotic and wound surface. The hemostatic effect is good, with less postoperative drainage fluid from pericardium and mediastinum than usual, and the ICU stay was 4 days. 【Conclusion】 Allogeneic platelets as a source of PRP to prepare PG may be applied to obtain the clotting and healing during surgical operation.
ABSTRACT
【Objective】 To explore the quality of autologous platelet-rich plasma prepared by manual and automatic method and to study the clinical injection therapeutic effects in patient with knee arthritis. 【Methods】 28 patients with knee arthritis in Orthopedics Department of our hospital were enrolled. PRP was prepared manually in 12 patients and automatically in 16. The whole blood of 50~70 mL was drawn from 12 patients and prepared into PRP of 10 mL manually by centrifugation. The 20~30 mL PRP was collected by automatic apheresis. Plt, RBC, WBC and other related indexes of PRP were detected after collection. Among the 28 patients, 12 in the manual group received injection twice, while 16 in the automatic group 4 episodes, with an interval of 15~20 days. The treatment effect was evaluated after the last treatment. 【Results】 The PRP prepared by two methods can both reach the required quality standard of platelet counts..The patient′s pain symptoms relieved significantly after injection treatment and the effect was remarkable. There was no significant difference in clinical efficacy between the two groups. 【Conclusion】 The PRP prepared by manual and automatic methods can be used for injection treatment for patient with knee arthritis. The clinical therapeutic effects were good and worth promotion and application.
ABSTRACT
Objective:To evaluate the effect of angiotensin-converting enzyme (ACE) gene polymorphism on dexmedetomidine-induced inhibition of responses to endotracheal intubation in the patients with hypertension.Methods:One hundred and eighty patients with essential hypertension, aged 48-61 yr, weighing 51-66 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, in whom ACE genotype was determined using polymerase chain reaction-restriction fragment length polymorphisms method before operation, were divided into 6 groups ( n=30 each) according to whether dexmedetomidine was applied: DD genotype group (DD group), ID genotype group (ID group), II genotype group (II group), dexmedetomidine plus DD genotype group (DEX+ DD group), dexmedetomidine plus ID genotype group (DEX+ ID group), and dexmedetomidine plus II genotype group (DEX+ II group). Dexmedetomidine 0.8 μg/kg was intravenously infused over 15 min before induction of anesthesia in DEX+ DD group, DEX+ ID group and DEX+ II group.Systolic and diastolic pressure (SP, DP) and heart rate (HR) were measured before dexmedetomidine (T 0), immediately before tracheal intubation (T 1), immediately after tracheal intubation (T 2), and at 1.5 and 5.0 min after tracheal intubation (T 3, 4). The rate-pressure product (RPP) was calculated.The occurrence of myocardial ischemia and cardiovascular responses within 5 min after tracheal intubation was recorded.Blood samples from the internal jugular vein were collected at T 0 and T 2-4, and plasma concentrations of epinephrine (E) and norepinephrine (NE) were determined by high performance liquid chromatography-electrochemical detection assay. Results:Compared with group DD, the SP, DP, HR and RPP were significantly decreased at T 2-4, plasma NE and E concentrations were decreased at T 2, 3, and the incidence of myocardial ischemia and cardiovascular reactions was decreased in group Dex+ DD ( P<0.05). Compared with group ID, SP, DP, HR and RPP were significantly decreased at T 2-4, plasma NE and E concentrations were decreased at T 2, 3, and the incidence of myocardial ischemia and cardiovascular responses were decreased in group Dex+ DD ( P<0.05). Compared with group II, SP, DP, HR and RPP were significantly decreased at T 2, 3, plasma NE and E concentrations were decreased, HR and RPP were decreased at T 4, and the incidence of myocardial ischemia and cardiovascular reactions was decreased in group Dex+ II ( P<0.05). There was no significant difference in the above parameters among group Dex+ DD, group Dex+ ID and group Dex+ II ( P>0.05). Conclusion:ACE gene polymorphism does not affect dexmedetomidine-induced inhibition of responses to endotracheal intubation in the patients with hypertension.
ABSTRACT
Objective To evaluate the effect of angiotension-converting enzyme (ACE) gene poly-morphism on dexmedetomidine-induced inhibition of responses to extubation in the patients with hyperten-sion. Methods A total of 180 patients with primary hypertension, aged 50-63 yr, weighing 54-69 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective abdominal surgery under general anesthesia, in whom ACE genotypes were detected using polymerase chain reaction-restriction fragment length polymorphism, were divided into 6 groups (n = 30 each) according to whether dexmedeto-midine was applied: DD genotype group (DD group), ID genotype group (ID group), Ⅱ genotype group (Ⅱ group), dexmedetomidine +DD genotype group (DEX+DD group), dexmedetomidine +ID genotype group (DEX+ID group) and dexmedetomidine+Ⅱ genotype group ( DEX+Ⅱ group). Dexmedetomidine 0. 5 μg·kg-1 ·h-1 was intravenously infused starting from 30 min before the end of surgery until the end of surgery in DEX+DD, DEX+ID and DEX+Ⅱ groups. Immediately before infusing dexmedetomidine (T1 ), at 30 min of dexmedetomidine infusion (T2 ), immediately after extubation (T3 ) and at 1. 5, 5 and 15 min after extubation (T4-6 ), systolic blood pressure, diastolic blood pressure, heart rate and ECG were recor-ded, and rate-pressure product was calculated. The development of myocardial ischemia and responses to extubation was recorded within 15 min after extubation. Results Compared with the baseline at T1 , each parameter of hemodynamics was significantly increased at T3-6 in DD, ID and Ⅱ groups (P<0. 05), and no significant change was found in each parameter of hemodynamics at T2-6 in Dex+DD, Dex+ID and Dex+Ⅱ groups (P> 0. 05). Each parameter of hemodynamics was significantly lower at T3-6 , and the inci-dence of myocardial ischemia and responses to extubation was decreased in group Dex+DD than in group DD and in group Dex+ID than in group ID (P<0. 05). Compared with group Ⅱ, each parameter of he-modynamics at T3-6 and incidence of responses to extubation were significantly decreased in group Dex+Ⅱ, and each parameter of hemodynamics was significantly increased at T3-6 , and the incidence of myocardial ischemia and responses to extubation was increased in DD and ID groups (P<0. 05). There was no signif-icant difference in each parameter of hemodynamics or incidence of myocardial ischemia and responses to extubation among group Dex+DD, group Dex+ID and group Dex+I (P>0. 05). Conclusion ACE gene polymorphism does not affect dexmedetomidine-induced inhibition of responses to extubation in the patients with hypertension.
