Pain Management in Pediatric Surgery - A Review

Introduction

Pain in pediatric patients or children presents various challenges because they communicate differently, and their thinking ability is very different compared to adults. It is very crucial to address this pain component to minimize discomfort and suffering for pediatric patients, especially the ones in surgery. It also improves the child’s overall hospital experience and long-term mental health. The main goal of pain management is to reduce pain, help movement, and resume daily activities after surgery. This article intends to discuss the different approaches to managing pain in pediatric patients.

How Is Pain Different in Pediatric Patients?

Various factors differ in pediatric patients, resulting in different pain perceptions. These include:

1. Physiological Differences: Children are small and have high metabolic rates compared to adult patients. These considerably alter the pain distribution and also the uptake of analgesic medication.

2. Cognitive Difference: Pediatric patients do not understand enough to perceive pain as they have an immature nervous system. Also, as the children cannot communicate properly, they may be unable to verbalize pain or accurately point out pain.

3. Parental Factors: Sometimes, parents' behavior also affects the child’s pain experience. Certain comfort toys can also affect the child's pain response.

Pediatric patients feel more pain due to all the above reasons and have less modulatory activity to control the pain. Moreover, their emotional state, markedly influenced by fear of what is going to happen or a previous traumatic experience, can make them perceive more pain. This increase in pain perception needs to be dealt with patiently and kindly.

How Is Pain Managed in Pediatric Surgery Patients?

1. Preoperative Management of Pain: It is important to take a thorough medical history of the patient regarding any painful condition or family history. Various pain assessment scales use smileys and images to gauge the pain. Any factors that can cause the child to be anxious are checked by educating them and answering their questions and queries. The child and parent must be educated about the various pain management techniques. Knowledge of what will be done considerably reduces anxiety and fear and improves cooperation. At certain times, certain sedative medications will be necessary preoperatively to reduce severe anxiety. The patient must be allowed to get comfort toys and take parental comfort whenever needed. This considerably helps at this stage. Older pediatric patients may be explained the procedure in a simpler manner, which will help them understand and cope better with the procedure.

2. Intraoperative Management of Pain: Intraoperatively, pain is mainly managed using appropriate anesthetics and techniques to ensure patient cooperation and analgesia throughout the procedure. The different anesthesia techniques utilized during pediatric surgery are :

General Anesthesia: General anesthesia is a pain management technique commonly used during surgeries. The patient is medically induced into an unconscious state so that he/she does not feel pain during the procedure. It is important to continuously monitor the patients in general anesthesia by checking their vital signs, oxygenation, and the level of anesthesia. The stages of anesthesia include:

3. Induction: This involves transferring from the awake to the unconscious state. Monitoring vital signs is to be done, and airway management is to be initiated at this stage.

4. Excitement: Here, the patient may show irregular breathing, involuntary movements, and increased reflexes. The airway must be secured properly to prevent the risk of aspiration.

5. Surgical Anesthesia: This is the target stage. Wherein the patient becomes fully unconscious with no feeling of pain or perception. The patient is continuously and carefully monitored to ensure all vitals are normal and the depth of anesthesia given is adequate.

6. Emergence: In this stage, anesthesia is reversed as the patient is awakened from the anesthetic state.

• Regional Anesthesia: It is a pain management technique in which a specific region of the body is numbed to prevent pain sensations. The patient using this technique will be lightly sedated or awake.
• Local Anesthesia: in this technique, the patient is awake. The surgical site is infiltrated with local anesthetics to provide immediate pain relief.

Postoperative Management: Non-pharmacological and pharmacological approaches can manage pain

Pharmacological Approaches:

• Analgesics

• Acetaminophen: Most commonly prescribed analgesic for pain relief. It is preferred as it has minimal side effects and drug interactions and, therefore, can be combined with other analgesics for faster pain relief. Moreover, it is safe for use in pediatric patients with mild to moderate.

• NSAIDs: Nonsteroidal anti-inflammatory steroids help manage a certain degree of pain and also have fewer side effects compared to opioids.

• Opioids: Moderate to severe pain. Morphine and Fentanyl are commonly used. Side effects to be considered include nausea, vomiting, and respiratory depression.

• Local Anesthetics: Sometimes, the surgeons decide to continue the use of epidural medications and nerve blocks locally after the surgery, too, to provide pain relief.

• Special Pain Management: Medications for chronic pain like Gabapentin and Amitriptyline are prescribed in certain cases after the surgery to provide relief of pain in the long term.

Non-pharmacological Approaches:

1. Physical Comfort: Numerous comfort measures like providing a calm environment, comfort toys, positioning in a position with less pain, and cold or warm compresses all help relieve pain.

2. Psychological Support: Various techniques, such as distraction, breathing, relaxation, and yoga, effectively relieve pain.

3. Behavioral Interventions: Various techniques, such as cognitive behavioral strategies like positive reinforcement and relaxation, can help children cope with pain.

4. Parenteral Support: The parents being with the child provides a calm and assured environment for the child and relieves the patient from anxiety and fear.

Conclusion

Successful pain management in pediatric surgeries depends on various factors and requires careful planning and different approaches based on child-to-child. Consideration should be made on the surgery to be performed, the age of the patient, and medical history. Best pain management is obtained by combining preoperative, intraoperative, and postoperative measures so that the patient and their caregiver do not feel discomfort and pain throughout. The healthcare professional must undertake pharmacological and non-pharmacological measures to ensure optimal pain relief, enhance the overall good experience, and promote a good hospital stay.
