Authors/citation Study purpose/ Research question Sample/ Participants Design Variables: Dependent Independent Procedures Analysis Results Recommendations Level of Evidence
Mukhopadhyay et al., 2010 This study has two purposes: The first purpose is to see whether a restrictive blood transfusion along with blood conservation system will decrease the amount of pack red blood cell transfusion. The second purpose is to see whether the blood conserving apparatus will conserve hemoglobin level from admission to discharge. Fore every single participant in the control group there are two intervention members. N=80 Participants in the control group and N=170 participants in the intervention group. The original numbers were 106 in the control, six …show more content…
Second: the need for transfusion in relation to the result of hemoglobin and hematocrit. Third: To check the effect it has on the arterial pressure monitoring waveforms. Fourth: To see if there is a change in the number of needle sticks. Total number of participants were 100 patients admitted to the Medical intensive care unit requiring arterial line monitoring. The control group received the normal pressure line monitoring N=50 and Active group with the venous arterial blood management system (VAMP) N=50. Exclusion criteria were active bleeding or chronic kidney disease on admission. Prospective Randomized Controlled Trial. Independent variable was using a venous, arterial blood management system (VAMP). Dependent variables: The effect of the device on the transfusion requirement, result of hemoglobin and hematocrit, change in the number of needle sticks and effect on arterial monitoring wave line. Study was done in the critical care unit of Northwestern Memorial Hospital. Patients were enrolled blindly into Either the control group or the active group "based on predetermined, random assignments contained in sealed, consecutively numbered envelopes" (p502). This was a 14 day study and the following data were gathered in both groups: "age, gender, discharge status, duration of ICU stay, time in the study, frequency and volume of the blood drawn for diagnostic testing; volume of blood discarded, every 12hrs hemoglobin and hematocrit (H&H) check" or mean H&H if it was stable the day before and no labs were drawn that day (p503). Two sample t-test and Chi-square test. Linear regression test to see the relation between hemoglobin and hematocrit. P (p506). Level II
