Pain is often inflicted on patients attending the Emergency Department (A&E) as they undergo common medical procedures, including venipuncture and cannulation intravenous. These procedures greatly affect patients due to the pain and discomfort they induce. Therefore, adequate procedural pain management is an important clinical goal that is often overlooked in the fast-paced emergency department environment. Say no to plagiarism.

Bloodletting, also known as venipuncture, refers to the puncture of a peripheral vein to draw blood and often involves the insertion of a peripheral intravenous line to provide patients with intravenous therapy or medications. When patients visit the emergency room, pain is often their primary complaint resulting in more than 40% of the 100 million or more emergency room visits each year. Once they arrive at the emergency room, patients often must undergo invasive procedures such as venipuncture to obtain blood and establish intravenous access for treatment. This has been shown to cause significant pain perceived by adult patients and is among the three most common painful procedures in adults in the emergency room. However, no anesthesia was used for the blood draw, while only 1.6% received anesthesia for the intravenous procedure. However, it is recommended that analgesic care be provided not only for complaints of adults presenting to the emergency department, but also for tests and procedures performed in the emergency department. Because the level of pain is so significant in adults when performing these necessary procedures, it is necessary to address inadequately treated pain. There are currently no measures taken to relieve the pain caused by bloodletting other than verbal reassurance. This is why it is important to introduce effective measures to control pain from procedures in emergency settings. Vapocoolant spray is one such intervention that should be promoted as it is convenient, easy to use, and efficient to apply to patients who come to the emergency room and require bloodletting. Since bloodletting refers to a vascular access procedure, emphasis in this thesis will be placed on both venipuncture and intravenous cannulation. Lack of pain management for procedural pain negatively affects adult patients physiologically and psychologically. Physiologically, patients may develop lightheadedness, dizziness, sweating, and even nausea. This can develop into a vasovagal attack evidenced by low blood pressure and decreased heart rate, resulting in fainting. Psychologically, bloodletting can cause adults to develop fear and anxiety, even before the procedure begins. Usually, the source of this anxiety is the anticipated pain caused by venipuncture or opening an intravenous access. There have been several incidents of adults undergoing bloodletting, experiencing pain from the procedure or being afraid of needles and developing vasovagal syncope as a result. This is not only unpleasant for patients, but can also cause anxiety regarding medical treatments and have a negative effect on them, solely due to the lack of effective pain management causing a gap in achieving optimal care for the patient. Furthermore, there are many adults who cannot tolerate pain and.
