  • Abdominal pain is a common presenting symptomin children. A substantial percent of unscheduledpaediatric office visits and paediatric emergency roomvisits are due to abdominal pain.... Scholer et alinvestigated the prevalence presenting complaints in children found that more than 63 childrens reported some kind of abd pain.....
  • Individual children differ greatly in their perception of & tolerance for abdominal pian ..this is one of the sevral reason why pediatric abd pain is Is difficult to deal with..A child with functional abdominal pain may be as uncomfortable as one with an organic cause… will be touching upon the following topics
  • Nociception differs from other sensation in that it sounds a warning that sumthing is wrong & it preempts other signals
  • Many of us think why treat pain if its causeless harmless ,I think q can be better answered by those who suffered from some or other kind of pain may it be severe abd pain of appendicitis or simple headache basically pain turns out to be a comlex. Any pain wen prolong results in alteration of physilogy ranging from hyperacidity to sleep disturbance the importance of pain is so much recognised that separate pain clinics are now well eastablished.
  • Pain can be explained on basis of 4 physilogical phenomenonTransduction is a process by which noxious stimuli are translated into electric signals at sensory n endings..performed Primary afferent fibers -synapse in the dorsal horn of spinal cordSecond order neuron in the lamina of the dorsal horn, ascending neurons projecting to brain stem,thalamus n thalamocortical projections. Transmission is a propagation of impulse through sensory n system by first aferentfibres which synapse in dorsal nerve & second order neurons in matrix of dorsal horne
  • a normal belief that newborns & children have less pain to noxous stimuli is very unphysilogical …..a newborn strts developing skin receptors and sensory nerve as early as 20 weeks ..while the inhibitory mechanism strt developing very slowly after 34 weeks…therefore pediatric pain of any quality & quantity may it b abdo pain or other shud never be overlooked
  • Clinically, abdominal pain falls into three categories: visceral (splanchnic) pain, parietal (somatic) pain, and referred pain…let us see the characteristics of eachThe difference in characteristics are because of different pathways n innervations at sensory end
  • Visceral pain occurs when noxious stimuli affect a viscus, such as the stomach or intestines. Tension, stretching, and ischemia stimulate visceral pain fiber .
  • Parietal pain arises from noxious stimulation of the parietal peritoneum . Pain resulting from ischemia, inflammation, or stretching of the parietal peritoneum is transmitted through myelinated afferent fibers to specific dorsal root ganglia on the same side and at the same dermatomal level as the origin of the pain. Parietal pain usually is sharp, intense, discrete, andlocalized, and coughing or movement can aggravate it.
  • Referred pain has many of the characteristics of parietal pain but is felt in remote areas supplied by the same dermatome as the diseased organ . It results from shared central pathways for afferent neurons from different sites . A classic example is a patient withpneumonia who presents with abdominal pain because the T9 dermatome distribution is shared by the lung and
  • Let us go through the causes o abd painsysem wise…in gi system in order of prevalnece
  • In a children with features suggestive of failure to thrive , recurrent abd pain following cause can be suspected
  • Drugs and toxins which can cause abd pain are erythro
  • Pneumonia @ diaphragmatic hernia are the pulm causes abd pain n operate through mech of reffered
  • The infant younger than 2 years old with abdominal pain is the most difficult to evaluate because the child cannot describe or localize the complaint
  • Similar to the infant ,the child who is 2 to 5 years of age usually has an organic cause of abdominal pain*The most common causes of abdominal pain are inflammatory process ,such as GE,and UTI
  • The preadolescent child add another dimension to the spectrum of abdominal pain- that of non organic or psychogenic illness The leading organic causes of abdominal pain still are inflammatory and include GE ,appendicitis and UTI
  • Some children have symptoms that do not fit the definition of organic disorders, functional dyspepsia, or IBS, and are thus described as having functional abdominal pain

  • TYPES OF ABDOMINAL PAIN Visceral Pain - Dull poorly localised, usually periumbilical Parietal pain - sharp, intense, discrete Referred pain - same features as parietal pain dnbpaediatrics.blogspot.in
  • Quick physiology of visceral pain !! dnbpaediatrics.blogspot.in
  • Pathophysiology visceral pain Tension, stretching, and ischemia stimulate visceral pain fiber. Tissue congestion and inflammation tend to sensitize nerve endings and lower the threshold for stimuli. Because visceral pain fibers are bilateral and unmyelinated and enter the spinal cord at multiple levels, visceral pain usually is dull, poorly localized, and felt in the midline.
  • Pathophysiology parietal pain Noxious stimulation of the parietal peritoneum Ischemia, inflammation, or stretching of the parietal peritoneum Myelinated afferent fibers to specific dorsal root ganglia on the same side and at the same dermatomal level Sharp, intense, discrete, and localized, Coughing or movement can aggravate it. dnbpaediatrics.blogspot.in
  • Pathophysiology referred pain  Many of the characteristics of parietal pain  Remote areas supplied by the same dermatome as the diseased organ  Shared central pathways for afferent neurons from different sites dnbpaediatrics.blogspot.in
