ABSTRACT:

Pain is the unpleasant sensory and emotional experience associated with actual or potential tissue damage, or decrease in terms of such damage. Early pain experiences may play a particularly important role in shaping an individual’s pain responses. In adequate relief of pain and distress painful medical procedures may have long-term negative effects on future pain tolerance and pain responses. Intravenous therapy is delivered annually to millions of patients in homes, hospitals and other health care facilities. Cannulation causes moderate or severe pain in a substantial number of children and adults.  Some institutions have procedures for minimizing the predictable pain of cannulation. Tropical anesthetics are analgesic drugs that may be associated with higher magnitude of benefit for managing pain during common needle stick procedures. In a study conducted to examine the difference in pain scores following tropical anesthetic and placebo application, a sample of 43 healthy adult volunteers experiencing IV catheterization were enrolled. The subjects were randomized to receive liposomal lidocaine cream on one hand and a hand cream on the other hand 30 minutes prior to IV catheterization. Pain scores were reported utilization a visual along scale (1-10cm) after intravenous cannulation and paired t-tests were used to measure the difference in pain scores between hands. The findings suggest that the tropical use of liposomal lidocaine anesthetic cram is a viable option for reducing the pain associated with IV catheter insertion in adults.

 

 

INTRODUCTION:

Pain is a highly unpleasant and very personal sensation that cannot be shared with others. It can occupy all a person’s thinking, direct all activities, and change a person’s life. Yet pain is a difficult concept for a client to communicate¹.

 

 

The differences in individual pain perception and reaction, as well as many causes of pain, present the nurse with a complex situation when developing a plan to relieve pain and provide comfort. Effective pain management is an important aspect of care.²

 

Pain is considered as the fifth vital sign. It occurs with many disorders, diagnostic tests, and treatments. Since nurses spend more time with the patient in pain than to do other health care providers, nurses need to understand the causes of pain implement pain relief strategies and evaluate the effectiveness of this strategies.³

 

McCaffery defines pain as “whatever the experiencing person says it is, existing whenever he or she says it does”. This definition emphasizes the highly subjective nature of pain and pain management. Basic to this definition is the care provider’s willingness to believe that the client is experiencing pain and that the client is the real authority on that pain.⁴

 

Intravenous therapy is delivered annually to millions of patients in homes, hospitals and other health care facilities. It is an effective method of supplying fluids directly into the intravascular fluid compartment and replacing electrolyte losses. The nurse is responsible for initiating, monitoring and discontinuing the therapy⁵.

 

It has been found to be true that intravenous cannulation is a painful and uncomfortable experience. Approximately 70% of adults and children feel fear, stress, depression, anger or anxiety prior to a needle stick procedure or venipuncture. One could therefore reasonably hypothesize that if a patient’s pain experience was decreased then they would feel less anxious about future cannulation. Many institutions have procedures for minimizing the predictable pain of intravenous cannulation. An effective method of decreasing this discomfort is the use of a topical local anesthetic cream.

Topical anesthetics are safe and effective for reducing the physical and emotional distress that may experience during painful procedures. Topical anesthetics in one form or another have been used for the past 20 years to alleviate the skin pain associated with needle puncture and venous cannulation. Topical anesthetics reduce pain by inhibiting the transduction and transmission of nerve impulses. This secondary to an alteration in transmission through voltage sensitive sodium channels, results in a rise of potential threshold. Traditional agents utilized as topical anesthetics for pediatric needle stick procedures are a mixture of local anesthetics, various lidocaine formulations, and vapocoolants.

 

Lidocaine Ointment 5% is a tropical preparation of lidocaine, local anesthetic that can be absorbed through the skin. This drug works by blocking the signals sent by nerves to tell the brain that the body is experiencing pain. Lidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action. Lidocaine ointment is recommended for situations like sunburns, rashes, and other lesions that cause pain, irritation or itching. While pain signals can be very valuable for the brain to receive when an injury is initially sustained, prolonged pain and irritation are not enjoyable and topical lidocaine can be used to make people more comfortable.⁶

 

Lidocaine Ointment 5% contains lidocaine, which is chemically designated as acetamide, 2-(diethylamino)-N-(2,6-dimethylphenyl)-, and has the following structural formula

 

 

Intravenous catheter placement is extremely painful common procedure performed in all ages and health care settings, more often than without anesthetic, despite clear research and guidelines demonstrating their effectiveness.

 

NEED FOR THE STUDY

Intravenous therapy and the care of vascular devices play a pivotal role in the delivery of modern health care treatments. Intravenous cannulation is the insertion of the cannula directly into the vein. It is the best way to deliver a precise dose quickly and in a well-controlled manner throughout the body. It is also used for irritation solutions, which would cause pain and damage tissues if given by subcutaneous or intramuscular injections.

 

It has been estimated than 70-80 % of all hospitalized parents receive some form of intravenous therapy via a variety of vascular access devices. Initially nurses were only allowed to add drugs to infusing bag, ensure maintenance of device, changing infusion fluid on time and reporting any abnormalities to medical staff. This has altered dramatically with the advances in vascular access device technology and the expanding role of the nurse. Now-a-days in many specialist areas the nurses play a crucial role in the selection, insertion and removal of both peripheral and central venous devices.⁶

 

Intravenous cannulation is a distressing and painful procedure for patients. More than 80 % of patients in acute care and outpatient surgical settings receive some forms of intravenous therapy. The need of an intravenous line raises the anxiety level of most patients whether the patients have had a previous intravenous line or not, they perceive an IV start as a painful procedure. Since the placement of an intravenous catheter is a fairly common invasive procedure, nurses should know what method can be used to alleviate some of the pain and anxiety.

 

OBJECTIVES OF THE STUDY:

1.    Assess the level of pain during intravenous cannulation among experimental group.

2.    Assess the level of pain during intravenous cannulation among control group.

3.    Compare the level of pain among experimental group and control group. 

4.    Associate the level of pain with the selected demographic variables among experimental group and control group.

 

MATERIALS AND METHODS:

Research design:

Experimental research design – Posttest only control group design

 

Setting:

The study was conducted at SPMM Hospital Salem district.

 

Population:

The patients admitted in the medical ward of SPMM Hospital who required an intravenous line electively

 

Sample:

60 samples from SPMM hospital

 

Sampling Technique:

The patients admitted in the medical ward of SPMM Hospital who required an intravenous line electively

 

Data Analysis:

The data were analyzed by using both descriptive and inferential statistical methods.

 

FINDINGS:

Ÿ  Majority of patients (30%) were in the age group of 21-30 years in the experimental group, where as in control group majority of patients (26.7%) were in the age group of 51-60 years.

Ÿ  Majority of patients were females: 53.3% and 60% in experimental group and control group respectively.

Ÿ  Majority of patients were Hindus: 60% and 66.7% in experimental group and control group respectively.

Ÿ  Majority of patients were married: 80% and 86.7% in experimental group and control group respectively.

Ÿ  Majority of patients were having only primary education: 33.3% and 50% in experimental and control group respectively.

Ÿ  Majority of patients were moderately built: 70% and 83.3% in experimental and control group respectively.

Ÿ  Majority of patients were inserted 20 gauge cannula: 73.3% and 90% in experimental and control group respectively.

Ÿ  Majority of patients have undergone cannulation in cephalic vein (50%) in the experimental group and majority of patients were undergo cannulation in the dorsal metacarpal vein (46.7%) in the control group.

Ÿ  Majority of patients had 1-5 times previous exposure to intravenous cannulation: 66.7% and 50% in experimental and control group respectively.

Ÿ  Majority of patients have no pain from any chronic disease: 96.7% and 100% in experimental and control group respectively.

Ÿ  In the experimental group, the mean pain score percentage was only 23.3% compared to the control group mean pain score percentage 35%. The difference in the mean pain score percentage was 11.7%. It reveals that the patients in the experimental group experienced lesser pain compared to the patients in the control group.

Ÿ  The independent “t” test computed between experimental and control group pain scores were statistically significant at 0.000 level of significance. The calculated “t” value (4.906) is greater than the table value, 1.96. this shows that the topical anesthetic is effective in reducing pain during intravenous cannulation.

Ÿ  There is a significant association between pain score and gender (P=0.000) among patients in the control group. Other socio-demographic variables did not have any statistical relation with the pain score of experimental and control group.

 

CONCLUSION:

The mean pain score percentage of experimental group is lesser then the mean pain score percentage of control group. It reveals that the experimental group experienced laser pain compared to the patients in the control group. The independent “t” test computed between experimental and control group pain scores were highly significant. This shows that the topical anesthetic cream is effective in reducing pain during intravenous cannulation. There is a significant association between pain score and gender (p=0.000) among patients in the control group. Other socio-demographic variables did not have any statistical relation with the pain score of experimental and control group.
