This prospective study evaluates the effect of abstaining from tourniquets on pain reduction during the venous puncture of the elderly people.
Almost 3 million people aged 70 and over are hospitalized once or more each year. The implementation of multiple treatments in these fragile patients, often poly-pathological requires a regular biological monitoring. For these patients, samples must be taken on average every two days.
This population often has a fragile venous capital due to reduced skin elasticity, undernutrition more or less associated with dehydration, the use of certain venous-toxic treatments and / or repetition of the gesture taking into account the monitoring biological closely related to long-term therapies.
With the aim of well-treatment and well-being, the reduction of patient pain is one of the major concerns of caregivers and in particular pain induced by treatment.
In children, the practice of harvesting without tourniquet is already frequent (18) and our preliminary study has confirmed us on the tourniquet as one of the acts responsible for the pain that the caregiver can possibly abstain.
No study had been conducted on this subject in the adult population and more particularly the elderly population. This prospective study evaluates the effect of abstaining from tourniquets on pain reduction during the venous puncture of the elderly people.

| Comparison of the maximum pain associated with venous puncture, in elderly patients with a visible or palpable vein depending on the method of sampling. | Assessment of maximum pain on examination (including pain from skin-vascular invasion and tourniquet pain)by the patient using a verbal numerical scale (EN) rated from 0 to 10. This measure concerns the 1st sampling as a whole, regardless of the number of attempts necessary to obtain it and their terms | At the end of the study, an average of 12 month |

| Fabric tourniquet |
| Procedure |
The blood sample is taken with a fabric tourniquet |
|
| Without tourniquet | Procedure | The blood sample is taken without tourniquet |
|
| Comparison of the number of cutaneous-vascular breaks necessary for obtain a blood sample, according to the venous sampling procedure | Compilation of the number of cutaneous-vascular ruptures performed until obtention of a sample sent to laboratory | At the end of the study, an average of 12 month |
| Comparison of the time taken to obtain a blood sample by caregivers, according to the venous sampling procedures | Measurement of the time required for this sample using timing from the moment the nurse is ready and until the end of the filling of the first tube sampled. This timing is performed by the caregiver himself and not by the third party who will collect the patient's pain and who is not present, in order to avoid any external influence linked to the performance of the gesture during the evaluation of the main criterion | At the end of the study, an average of 12 month |
| Comparison of the ease of taking the sample by caregivers, according to the venous sampling procedure | Collection of the ease of performing the sampling by the caregivers via a Likert-type question (very easy, rather easy, rather difficult, very difficult) filled in after each sampling. In addition, the need to change arms or to call on another caregiver to perform the procedure will be noted. | At the end of the study, an average of 12 month |
| Estimation of the pain due to the tourniquet and to the cutaneous-vascular breaks in patients where sample was taken with tourniquet | Verbal numerical scale measurements of tourniquet pain and pain due to vascular break (groups with tourniquet only). 0 = No pain, 5 = moderate pain and 10 = Worst possible pain. | At the end of the study, an average of 12 month |
| Comparison of the frequency of side effects: malaise, hematoma at the cutaneous-vascular break site, according to the venous sampling procedure ; hematoma and / or skin abrasion at the tourniquet, in patients collected with tourniquet | The presence of hematoma (s) will be observed in each group the next day of the sample by a caregiver separate from the one who performed the sample. The caregiver will also note the presence of skin abrasions related to possible use of tourniquet. Other unwanted events will also be collected, in particular: vagal unease during or after the sample, hemorrhage, ... | At the end of the study, an average of 12 month |
| Comparison of the frequency of hemolysis of the sample, according to the venous sampling procedure | Proportion of samples having to be carried out again for hemolysis | At the end of the study, an average of 12 month |
| Estimation of the influence of the nurse's experience on the efficiency of venous sampling on the duration of blood collection | Estimation of the effect of the mode of venipuncture (arm), according to the experience of the nurse on the duration of blood collection. The duration of the blood sampling is expressed in minute. | At the end of the study, an average of 12 month |
| Estimation of the influence of the nurse's experience on the efficiency of venous sampling on pain | Estimation of the effect of the mode of venipuncture (arm), according to the experience of the nurse on pain. Verbal numerical scale measurements was used : 0 = No pain, 5 = moderate pain and 10 = Worst possible pain. | At the end of the study, an average of 12 month |
| Estimation of the influence of the type of material used on the efficiency of venous sampling on pain | Estimation of the effect of the mode of venipuncture (arm), according to the type of material (butterfly needle, diameter) on pain. Verbal numerical scale measurements was used : 0 = No pain, 5 = moderate pain and 10 = Worst possible pain. | At the end of the study, an average of 12 month |
