The cartilage of the first rib articulates directly with the manubrium of the sternum and is a synarthrodial joint that allows a limited gliding movement. The cartilage of the second through sixth ribs articulates with the body of the sternum via true arthrodial joints. The eighth, ninth, and tenth ribs attach to the costal cartilage of the rib directly above. The cartilages of the 11th and 12th ribs are called floating ribs because they end in the abdominal musculature (Fig. Weakness of the costosternal, costochondral, and occasionally the costovertebral joints may contribute to the development of slipping rib syndrome by allowing hypermobility of the ribs. Most often involving the tenth rib, and sometimes the eighth and ninth ribs, slipping rib syndrome is almost always the result of trauma to the anterior costal cartilages. Patients suffering from slipping rib syndrome complain of sharp, knife-like 657 pain with any movement of the lower anterior cartilages. The patient may also note a clicking, snapping, or catching sensation with movement of the anterior costal cartilages or with deep inspiration. On physical examination, the patient suffering from slipping rib syndrome will often exhibit splinting of the affected cartilages by forward flexing the thoracolumbar spine. Palpation of the affected anterior costal cartilages will cause pain as will the hooking maneuver test (Fig. The hooking maneuver test is performed by having the patient lie in the supine position with the abdominal muscles relaxed while the clinician hooks his or her fingers under the lower rib cage and pulls gently outward. Pain and a clicking or snapping sensation of the affected ribs and cartilage indicate a positive test. Patients suffering from slipping rib syndrome will also exhibit a positive ultrasound slipping rib test on transverse ultrasound imaging of the affected rib. The ultrasound slipping rib test is performed by imaging the rib and associated anterior costal cartilage suspected of slipping with the patient’s abdominal wall completely relaxed and then having the patient perform a vigorous Valsalva maneuver. The test is positive if the affected rib moves cranially and overlaps the rib above it (Fig. If the anterior costal cartilage and adjacent ribs are intact, under ultrasound imaging, with vigorous Valsalva maneuver, the adjacent ribs will be seen to move in concert downward (Fig. The hooking maneuver test for slipping rib syndrome is performed by having the patient lie in the supine position with the abdominal muscles relaxed while the clinician hooks his or her fingers under the lower rib cage and pulls gently outward. Pain and a clicking or snapping sensation of the affected ribs and cartilage indicate a positive test. B: When rectus muscle (rm) contraction is initiated, the eighth rib moves cranially and overlaps the seventh rib (curved arrow). D: At maximal contraction, the two ribs are at the same depth, below the rectus muscle. E: As the contraction decreases, the eighth rib jumps away from the seventh rib (arrow).

Slipping rib syndrome: a place for sonography in the diagnosis of a frequently overlooked cause of abdominal or low thoracic pain. Based on the patient’s clinical presentation, additional testing may be indicated, including complete blood cell count, prostate-specific antigen, sedimentation rate, and antinuclear antibody testing. Computed tomographic, magnetic resonance, or ultrasound imaging of the affected ribs and cartilage is indicated to help confirm the diagnosis of slipping rib syndrome and to help identify occult mass and/or lower intrathoracic or upper intra-abdominal tumor (Figs. Computed tomographic image demonstrating infarction of the hepatic flexure of the colon secondary to avulsion of the mesenteric artery following blunt upper abdominal trauma. The anterior costal cartilage and associated ribs at the level to be blocked are then identified by palpation. A linear high-frequency ultrasound transducer is then placed in the transverse plane with the superior aspect of the ultrasound transducer rotated approximately 15 degrees laterally over the affected costal cartilage and rib and an 659 ultrasound survey scan is obtained (Figs. The rib will be identified as a slightly hyperechoic ovoid structure with a hypoechoic center. The affected costal cartilages and associated ribs are then identified by the ultrasound slipping rib test (Figs. Longitudinal placement of the ultrasound transducer over the anterior costal cartilage and associated ribs with the superior aspect of the transducer rotated laterally approximately 15 degrees. Longitudinal ultrasound image demonstrating the adjacent ribs and the rectus muscles. Reassurance is required, although it should be remembered that this musculoskeletal pain syndrome and intra-abdominal pathology can coexist. One of the challenges in the treatment of the patient suffering from slipping rib syndrome is the fact that repeated abnormal movement of the affected rib segments promotes ongoing laxity of supporting ligaments and cartilage of the ribs delaying healing of the problem. Slipping rib syndrome: a place for sonography in the diagnosis of a frequently overlooked cause of abdominal or low thoracic pain. The muscle fibers of the diaphragm converge on a strong central aponeurotic tendon. The superior surface of the dome of the diaphragm serves as the floor of the thoracic cavity, with the inferior potion of the dome serving as the roof of the abdominal cavity. The musculofibrous fibers of the central portion of the diaphragm attaches anteriorly to the xiphoid process, with the ventral aspect of the diaphragm attaching laterally to the costal cartilages of the seventh through twelfth ribs as well as the transverse processes of the first lumbar vertebra and the vertebral bodies of the first through third lumbar vertebra (Fig. Peripherally the diaphragm attaches to the lower confines thoracic outlet by a musculotendinous structure called the diaphragmatic crura (Fig. The crura attach anteriorly and laterally to the thoracic wall, with the posterior portion of the diaphragm attaching into the posterior abdominal wall, which means that the diaphragm is set obliquely relative to the coronal plane with the anterior portion of the diaphragm attaching superiorly when compared with the posterior portion (Fig. The top of the dome-shaped portion of the diaphragm lies in a roughly horizontal plane relative to the thoracic and abdominal viscera when in a relaxed state. As the dome-shaped portion curves down to attach to the thoracic and abdominal walls, the diaphragm assumes a more vertical position relative to the thoracic and abdominal viscera as it attaches to the thoracic and abdominal wall. This vertical area is called the zone of apposition as the vertical portion of the diaphragm is apposed to the abdominal contents (Fig. The diaphragm is a fibromuscular, elliptically shaped cylinder that is capped by a dome that separates the thoracic and abdominal cavities and functions as the main muscle of respiration.
One must be aware that a bounding pulse does not necessarily denote good perfusion discount 3 ml careprost visa 7 medications that cause incontinence. The loss of central pulse is a premorbid sign and is to be treated as cardiac arrest 3ml careprost overnight delivery symptoms inner ear infection. Temperature: When the ambient temperature is warm buy careprost once a day symptoms 7 dpo bfp, the extremities should be warm. Assessment of the temperature of the trunk and the extremities should be done simultaneously as cooling occurs from the periphery to the center. Color: Color of the skin reflects skin perfusion and indirectly respiratory and circulatory status. Skin of palm and fingers may be pink (normal), pale, cyanosed, mottled or ashen grey depending on the degree of compromise. The extremity being tested should be raised above the level of the heart to make sure that only venous refill is not being tested. Brain: Brain perfusion can be assessed by features already described in appearance, i. Renal: Urine output may not be useful in initial assessment in a critically ill child, but is useful in monitoring the child and in evaluation of renal perfusion. Blood pressure: Shock can be present with normal, increased or decreased blood pressure. Progression to irreversible/refractory shock or multiple organ failure or death rapidly follows. Lower limit (5th percentile) of blood pressure is: Newborn 60 mm Hg systolic Up to 1 year 70 mm Hg systolic 2 to 10 years 70 + (2 × age in years) mm Hg Beyond 10 years 90 mm Hg systolic Pulse Oximetry Oxygen saturation assessment is an important adjunct to identify oxygenation state in an acutely ill child. Based on the appearance, breathing and circulatory status, the physiologic status of a critically ill child is classified as: 1. Cardiorespiratory failure is characterized by agonal respirations, bradycardia and cyanosis. Based on this physiologic status the severity of the compromise is classified and the child is managed further accordingly. For example; if a fluid bolus has been given then assess the child for any improvement as indicated by improved capillary refill, stronger pulses, improved urine output and a lower heart rate. Stabilization Depending on the physiologic status of the child, the following stabilization measures can be undertaken. Airway It should be assessed whether the airway is maintainable or unmaintainable. If the airway is unmaintainable, nasopharyngeal or oropharyngeal airway or intubation is required. The patency of the airway is to be assessed and excessive secretions should be cleared. Breathing Hundred percent oxygen should be provided to any critically ill child irrespective of the physiologic status. If the child has Respiratory Distress the child is kept with the caregiver, is allowed to maintain a position of comfort, and oxygen is provided in a non-threatening manner. Turbulent airflow leads to increased airway resistance; hence the child should be kept calm. In case of inadequate chest expansion or respiratory arrest, bag and mask ventilation should be given with 100 % oxygen. Tracheostomy or cricothyrotomy may be required in cases of complete upper airway obstruction caused by diphtheria, severe orofacial injuries or laryngeal fractures. Circulation Once airway and breathing have been stabilized, vascular access is to be secured. Any drug can be infused using this route provided it is followed by a flush of fluid to get the drug in the central circulation. Blood products should be administered only when specifically indicated for replacement o f blood loss or for replacement of components. When the circulation does not improve with fluid boluses alone, inotropes are used. During stabilization the priority is to address the Airway first followed by Breathing and Circulation.

Cerebral resuscitation after traumatic brain injury and cardiopulmonary arrest in infants and children in the new millennium. Critical illness causes alteration of physiologic status and biochemical parameters. The relationship between physiologic status and mortality risk may change as new treatment protocols, therapeutic interventions and monitoring strategies are introduced. Contribution of each variable and its ranges to mortality prediction were evaluated and the system was derived. The physiologic variables and their ranges were re-evaluated, eliminating some ranges that did not contribute significantly to mortality risk. A formal, operational method for assessing mental status is also included to account for frequent use of sedation and paralysis. The likely reasons for this could be difference in patient profile and greater load of severity of illness managed with lesser resources, both physical and human and also difference in quality of care. But there is no clear-cut threshold that directly predicts mortality and categorization of patients into different levels of risk is not possible.

This information is useful for optimum interventions and treatment to improve the outcome of critical illness. Tissue oxygenation is determined by the formula: O2 delivered = O2 carrying capacity of blood × cardiac output = ( Hb in gm × 1. In adults, the stroke volume can increase significantly while in the pediatric age group there are minimal stroke volume reserves and increased heart rate compensates maximally. If the demands increase beyond the compensatory mechanisms (decompensation), tissue oxygenation is jeopardized and anaerobic metabolism ensues with generation of lactate–the cascade of metabolic acidosis–negative inotropism–circulatory maldistribution is stimulated and ends up in multi-organ failure. In a stressful condition this failure cascade can be prevented or at least delayed, by timely oxygen supplementation.
