Objectives for this lecture

Identify elements of pain and phases of nociceptive pain.
List and apply concepts of pain in pediatric populations.
Identify blood and lymphoid organ structures and functions.
Verbalize HIT pathophysiology, at least three causes of DIC and alterations in erythrocyte function.
Verbalize neonatal hematology and identify skin alterations specific to pediatric populations.

Nociceptors

Nociception is the processing of harmful stimuli in an abnormal functioning nervous system
Nociceptors (pain receptors) are free nerve endings in the afferent peripheral nervous system
The nervous system, responsible for pain sensation, perception, and response, comprises three parts: afferent pathways, interpretive centers, and efferent pathways.

4 Phases of Nociception

Pain transduction, pain transmission, pain perception, and modulation.

Differences Between Acute and Persistent Pain

Characteristic | Acute Pain | Persistent Pain
--|---|---
Onset | Sudden | Gradual or sudden
Duration | Usually within the normal time for healing | May start as acute, but persists past normal healing time
Severity | Mild to severe | Mild to severe
Cause of Pain | A precipitating illness or event | May not be known
Course of Pain | Decreases over time and goes away | Pain persists and may be ongoing, episodic or both
Types of Physical and Behavioral Manifestations | Increased HR, RR, BP, diaphoresis, pallor, anxiety, agitation, confusion | Changes in affect, decreased physical movement and activity, fatigue, withdrawal

Stimuli that Activate Nociceptors (Pain Receptors)

Location | Stimuli
--|---|---
Skin | Pricking, cutting, crushing, burning, freezing
GI Tract | Engorged or inflamed mucosa, distention or spasm of smooth muscle, traction on mesenteric attachment
Skeletal Muscle | Ischemia, injuries of connective tissue sheaths, necrosis
Joints | Synovial membrane inflammation
Arteries | Piercing, inflammation
Head | Traction, inflammation, displacement of arteries, meningeal structures, and sinuses; prolonged muscle contraction
Heart |Ischemia and inflammation
Bone | Periosteal injury: fractures, tumor, inflammation

Pain Assessment

Goals: describe the patient's sensory, affective, behavioral, cognitive, and sociocultural pain experience for implementing pain management, identify patient's goal for therapy, and resources/strategies for effective self-management.
Sensory-descriptive component: pain pattern, area, intensity, and nature of pain.
Motivational-affective, behavioral, cognitive-evaluative, and sociocultural components of pain.
Assessment tools include: visual analog scale, numerical rating scale, faces pain scale.

Categories of Pain

Neurophysiologic pain (nociceptive and neuropathic pain), Neurogenic pain (neuralgia), Regional pain (abdominal, chest, orofacial, pelvic pain), Etiologic pain (cancer, dental, inflammatory, ischemic, or vascular pain). Temporal pain (time-related pain with acute and chronic durations)

Assessment of Acute Pain in Pediatrics.

Causes include medical procedures, treatments, injuries, infections, exacerbation of conditions like arthritis or sickle cell disease, and cancer.
The intensity evaluation should utilize behavioral measures, physiological measures, and self-report measures. This method is age-dependent.

Developmental Characteristics of Children's Responses to Pain

Responses vary by age.
Young infants may exhibit generalized body responses like rigidity.
Older infants may display localized body responses.
Older children may stall, display verbal expression of discomfort or request comfort or cessation of the procedure.

Hematology

The presentation discusses heparin-induced thrombocytopenia, disseminated intravascular coagulation, anemia, polycythemias, and alterations in leukocyte function.

Structure and Function of Blood

Blood is composed of plasma (albumin, globulins) and cellular components (erythrocytes, leukocytes, granulocytes, agranulocytes, platelets)

Structure and Function of Lymphoid Organs

Primary lymphoid organs: thymus and bone marrow
Spleen: critical component in the blood
Lymph nodes

Platelets

Platelets regulate blood flow, halt bleeding, activate the coagulation cascade, and facilitate clot repair.

Alterations of Platelet Function

Clinical manifestations include spontaneous petechiae, purpura, and bleeding from GI tract or other mucous membranes
Causes that affect platelet function include chronic renal failure, liver disease, cardiopulmonary bypass surgery, deficiencies in iron or folate, autoimmune disorders and hematological disorders.

Disorders of Platelets: Heparin-Induced Thrombocytopenia (HIT)

Typically occurs with IV heparin or LMWH.
Immune-mediated.
Starts 5-10 days after heparin administration.
Thrombocytopenia and potential for thrombotic events (DVT, PE, limb ischemia) necessitate clinical observation, laboratory monitoring, and alternative anticoagulants.

Disorders of Coagulation

Impaired hemostasis, inability to produce stable fibrin clots, associated with vitamin K deficiency/liver disease, consumptive thrombohemorrhagic disorders and Disseminated intravascular coagulation (DIC)

Disorders of Coagulation: Disseminated Intravascular Coagulation (DIC)

An acquired and activated systemic coagulation syndrome.
Results from damage to the endothelial lining of vessels, extensive fibrin clot formation, leading to organ dysfunction, and a consumption coagulopathy
Etiologies include sepsis, malignancy, infections, intravascular hemolysis, transfusion reactions, drug-induced hemolysis, pregnancies, medical devices, hypoxia, and arterial hypotension.
Pathophysiology involves the activation of the clotting cascade in response to vascular endothelial damage, cytokine and platelet activation factors, and tissue factor, leading to the consumption of clotting factors and platelets, promoting bleeding.

Hematological Conditions

This category includes anomalies related to blood components: anemia, polycythemia, leukocyte abnormalities, neonatal hematology, and skin alterations.

Hematological Conditions: Anemia

Characterized by low erythrocyte count or volume.
Caused by altered production, blood loss, increased erythrocyte destruction, combined factors, and alterations in erythrocyte shape/size/substance.

Hematological Conditions: Polycythemia

Excessive red blood cell production, two primary types (relative and absolute, the latter involving abnormal bone marrow stem cell proliferation)

Alterations in Leukocyte Function

Leukopenia relates to decreased leukocyte levels due to infectious processes and marrow suppressors.
Leukocytosis relates to increased leukocytes due to infection or myeloproliferative disorders.

Neonatal Hematology and Skin Alterations

Discusses hemolytic disease of the newborn (HDN) due to Rh incompatibility, its pathophysiology, diagnostic evaluation, and clinical manifestations, and skin alterations which are distinct features of the pediatric population.

Skin Alterations

The physical examination of skin involves observations of various lesion types, distribution, progression over time, and associated signs and symptoms.
Classifications of skin lesions may be primary (macule, papule, vesicle, bulla, plaque, nodule, pustule) or secondary (ulceration, erosion, keloid, scale, fissure, scar).
Possible etiologies for generalized/localized rashes include drug eruptions, viral infections, toxins, immunologic conditions, chemical irritation, hives, lice and other parasites.
Evaluation of rashes often relies on details of distribution, morphology, associated symptoms and potential medical history.

Key Points to Remember

The presentation emphasizes the knowledge and application of pathophysiology and clinical assessment related to hematopoietic, coagulation, and skin disorders and includes considerations of the pediatric population.
