All injections should be administered within the four quadrants of the abdomen. Rotate in the following order: lower left quadrant, lower right quadrant, upper left quadrant, and upper right quadrant. Use a 29 gauge needle. The syringe is used to administer the composition from the vial. The folds are pinched according to the target, and the needle is inserted at an angle of approximately 45 degrees. The second person uses a stopwatch to measure the length of the injection time. The target is 0.5m. Slowly push the plunger of the syringe until the composition L is injected. The target duration is 4 seconds, and no more than 5 seconds. The needle is removed from the skin after injection. The skin is released from the pinch of the target. The target is assessed for pain immediately after each injection. The measurement is assessed using a 100mm validated visual analog scale (VAS) for pain. VAS is a well-validated tool for evaluating injection site pain (Willi amson, A.; Hoggart, B. Pain: A review of thre e commonly used pain rating scales.Journ al of Clinical Nursing 2005,14,(7),798-8 04). VAS uses language descriptors, typically "no pain" and "worst pain imaginable." Therefore, it is presented as a fixed, 10cm (100mm) line. The subjects were marked on the 100mm line, indicating pain intensity at each point in time as clinically relevant. This is required. Staff members use calipers to perform VA on a target from scratch. Measure the distance to the mark placed on S and record the measurement in the source document. The results from the trial are shown in Table 8. The acceptable patient experience at injection sites is (moderate or This is reflected by an index of mild pain intensity (compared to severe pain).
