Possible sources of loud noise for a neonate nursed within an incubator are objects being placed on the incubator roof and closure of the incubator doors cheap 400 mg indinavir free shipping. Respiratory and cardiovascular pathology Respiratory difficulty or distress frequently presents during the neonatal period and has a variety of causes discount indinavir 400mg on-line. An important factor in the differential diagnosis of underlying pathology is the time at which symptoms of respiratory distress occur2 (Table 6. Transient tachypnoea Transient tachypnoea of the newborn is an ill-defined but common condition thought to result from a delay in the clearing of amniotic fluid from the lungs6. Symptoms typically manifest within 3 hours of birth and a clinical diagnosis is 98 Paediatric Radiography Table 6. Onset: birth–6 hours Onset: >6 hours post-delivery Onset: any time after birth Transient tachypnoea Pneumonia Upper airway obstruction Hyaline membrane disease Congenital heart disease Neurological disorders Meconium aspiration Underlying metabolic illness Pneumothorax Persistent pulmonary hypertension Congenital malformations Fig. Chest radiography under- taken within a few hours of birth may show evidence of hyperinflation, pleural effusion, fluid within the fissures, streaky opacification and prominent vascular markings6 (Fig. However, these radiographic findings are also consistent with neonatal pneumonia and further radiographic examinations may be required to monitor the progress of the condition. Complete clinical and radio- graphic resolution of transient tachypnoea should occur within 24 hours. Surfactant diminishes alveolar surface tension thereby preventing atelectasis (collapse) of the alveoli and acini and assisting in the maintenance of normal respiratory function. The 7 incidence of HMD is directly related to gestational age at the time of birth with very pre-term babies being most at risk. Clinical symptoms of HMD include cyanosis, tachypnoea, expiratory ‘grunting’ and intercostal retraction8. Regular radiographic assessment is likely to be requested to monitor the progress of the disease. Radiographically, the lungs are under-inflated and appear opaque or mottled, although air bronchograms may be evident (Fig. Meconium aspiration Meconium is a dark green discharge that results from the ‘sloughing off’ of dead bowel wall cells during foetal development. It is contained within the intestines of the full-term foetus and is usually passed within 24 hours of delivery. However, if foetal distress should occur during delivery then evacuation of meconium into the amniotic fluid may occur and in a small amount of cases (1%), aspiration of the meconium will result8 causing respiratory obstruction (air trap- ping) and distress. Radiographic examination of the neonatal chest will reveal hyperinflated lungs and patchy, bilateral opacification2 which may become more diffuse as the condition progresses (Fig. Clinically, symptoms of respiratory distress as a result of meconium aspiration resolve within 3–5 days of delivery although radiographic resolution may take up to 1 year. Pulmonary interstitial emphysema Surfactant deficiency in the premature neonate may result in the rupture of small airways and dissection of air into the interstitial space where it forms small cysts within the interlobular septae (pulmonary interstitial emphysema). The neonate may present asymptomatically or display signs of gradual degeneration and pro- gressive hypoxaemia if the condition is diffuse. Radiographic evidence of the condition includes areas of translucency and atelectasis (collapse). Pneumothorax Pneumothorax is a common complication of ventilator therapy, particularly if high pressures have been used. If the pneumothorax is large then the neonate will suffer respiratory difficulty and display signs of general deterioration. In these circumstances, a clinical diagnosis can be made following physical exam- ination. In contrast, small pneumothoraces may be asymptomatic and remain undetected until discovered incidentally on a chest radiograph. Radiological 100 Paediatric Radiography (a) (b) Fig. In cases where radiological diagnosis is uncertain, a horizontal beam lateral chest projection with the patient supine may be undertaken to demonstrate retro- sternal air (Fig. However, the radiographer must remember to reduce the selected kV and mAs appropriately to prevent over exposure of the retrosternal region.

No athlete should return to play while any symp- toms are still present either at rest or with exertion. No athlete should return to play on the same day if POTENTIAL LIFE THREATENING/ the concussion involved an LOC (even if brief) or DISABLING INJURIES if postconcussive symptoms are still present 15–20 min after the injury. An athlete with a mild concussion (Grade 1) with no LOC and resolution of PCS within 15–20 min Head injuries in sports are quite common and often both at rest and with provocative exertional maneu- provoke anxiety and uncertainty. Fortunately, the vers may safely return to play that same day, pro- most common head injury in sports is a concussion vided this was the first concussion. Regardless of whether an athlete returns to play or loss of consciousness (LOC) (McAlindon, 2002; is disqualified from play for that day, frequent Harmon, 1999). The FP must learn not only how to reevaluation and serial examinations are absolutely recognize them (which is not always easy) and mandatory. Assessment temporoparietal region and is associated with a skull for potential spine injury should be done, and once on fracture 80% of the time. Athletes will often experi- the sidelines, a full neurologic examination performed, ence a brief LOC followed by a lucid interval which including a full sensory, motor, and cranial nerve may last up to several hours, and then progress to examination as well as cognitive functioning and rapid neurologic deterioration and eventually coma memory testing. Treatment is surgical and Obvious signs of skull fracture or intracerebral bleed- immediate transfer to a medical facility is required. It must be emphasized that the symptoms of a first head injury have resolved. CHAPTER 4 FIELD-SIDE EMERGENCIES 15 A controversial topic, it is a catastrophic injury that Although there are no definitive guidelines as to may occur because of a loss of cerebral autoregulation which athletes with neck injuries are safe to return to caused by the initial injury (Harmon, 1999; Crump, play, it is generally agreed on that only those players 2001; Graber, 2001). When the second injury occurs, with absolutely no neck pain or neurologic symptoms and it is often a very mild injury, cerebral edema rap- and with completely normal examinations may return idly develops with subsequent brainstem herniation to play safely, with repeated evaluation being within a matter of seconds to minutes. Treatment con- absolutely necessary (Haight and Shiple, 2001; sists of immediate intubation and hyperventilation, McAlindon, 2002). Despite aggressive treatment, mortality and morbidity are around 50% OPHTHALMOLOGIC INJURY and 100% respectively (Cantu, 1998; 1992). Examination of the eyes should include an assessment of visual Neck injuries, although relatively uncommon and acuity, visual fields, the eyelids and periorbital bony usually self-limited (McAlindon, 2002), represent structures, the surface of the globe (conjunctiva, one of the most feared and potentially catastrophic sclera, cornea), the pupils (size, shape, reactivity), injuries in sports. The FP must promptly recognize extraocular movements, and fundoscopic examination the potential for spine injury, adhere strictly to spinal and possibly intraocular pressure measurement as precautions (discussed previously in this chapter), indicated (Cuculino and DiMarco, 2002 ).

However buy 400 mg indinavir fast delivery, similar results have been reported in two such RCTs (Doering et al indinavir 400mg fast delivery. An information provision intervention- (sensory and procedural) delivered in person to patients undergoing gyne- cological laparoscopic surgery did not reduce pain levels postsurgically compared to no-intervention controls (Reading, 1982). Despite this lack of effect on pain reports, a behavioral effect was observed, with intervention- group patients requesting significantly fewer analgesic medications (Read- ing, 1982). More recently, Doering and colleagues examined the efficacy of a procedural information videotape intervention in patients undergoing hip replacement surgery (Doering et al. Results of this RCT also revealed no significant effects on pain intensity ratings, although like the Reading (1982) study, significant reductions in analgesic requirements were ob- served (Doering et al. Results of studies such as these indicate some potential postsurgical benefit of information provision interventions. Clinical Trials in Children Although not a primary focus of this chapter, it is important to note that psychological interventions appear to have benefit in the control of acute pain associated with medical procedures in children as well as adults. A meta-analysis (total of 19 studies) of the effects of techniques including dis- traction, relaxation, and imagery on acute pain experienced during medical procedures in children indicated a significant overall clinical effect, with children receiving interventions on average reporting pain levels 0. Children required to undergo repeated lumbar punctures or bone-mar- row aspirations as part of cancer treatment have been the focus of a num- ber of the available RCTs. These studies indicate the efficacy of combined interventions, including breathing relaxation, imagery, and distraction, for 258 BRUEHL AND CHUNG reducing the pain associated with such procedures (Jay, Elliott, Katz, & Siegel, 1987; Jay, Elliott, Woody, & Siegel, 1991; Jay, Elliott, Fitzgibbons, Woody, & Siegel, 1995; Kazak et al. These pain reductions appear to be clinically meaningful: Children receiving such a combined intervention reported 25% less pain than children in an attentional control group (Jay et al. Psychological interventions may also be effective for less intense but more common sources of acute clinical pain in children. For example, a sim- ple distraction intervention (use of a kaleidoscope) resulted in significantly reduced pain and distress associated with venipuncture relative to a group given simple comforting responses by clinicians (Vessey, Carlson, & McGill, 1994). Despite positive results such as these, other studies examining dis- traction and controlled breathing interventions for venipuncture pain indi- cate selective effects, reducing emotional distress during venipuncture but not affecting pain intensity significantly (Blount et al. As a whole, controlled trials in children do suggest some benefit to the use of psychological interventions for acute pain. COMPARISONS WITH PHARMACOLOGICAL PAIN MANAGEMENT The results of several of the outcome studies just reviewed indicate that psychological interventions used in conjunction with pharmacological ap- proaches may reduce the amount of such analgesic medications required (Ashton et al. Direct comparisons of psychological to pharmaco- logical techniques for acute pain management are rare and frequently suf- fer from methodological limitations, making interpretation difficult (Geden, Beck, Anderson, Kennish, & Mueller-Heinze, 1986; Kolk, van Hoof, & Dop, 2000; Schiff, Holtz, Peterson, & Rakusan, 2001). In the context of relatively mild acute pain associated with venipuncture, evidence for the benefits of distraction interventions compared to topical anesthetic interventions is mixed. A similar study also suggested no specific benefit (in terms of pain ratings) for a distraction intervention compared to a “standard care” condition, which frequently included EMLA cream (Kleiber, Craft-Rosenberg, & Harper, 2001). For children all of whom were provided with a distraction inter- vention, no differences in pain ratings were reported between those receiv- 9. PSYCHOLOGICAL INTERVENTIONS FOR ACUTE PAIN 259 ing EMLA versus those receiving placebo cream, suggesting no additive benefit of EMLA beyond distraction (Lal, McClelland, Phillips, Taub, & Beat- tie, 2001). Lack of statistical power does not account for the differences be- tween these studies, as the study with the largest sample size (n = 180) re- ported the most negative results (Arts et al. These studies do not indicate whether other psychological strategies, such as brief relaxation or imagery, may have been more effective than distraction relative to the pharmacological approach. However, these studies suggest that for brief, low-intensity procedures in which simple pharmacological interventions with minimal side effects (e. Several of the most methodologically sound controlled trials, all con- ducted in children, comparing psychological interventions with a pharma- cological intervention have been reported by Jay and colleagues (1987, 1991, 1995). Results indicated that the psychological intervention re- sulted in lower pain, distress, and physiological arousal than either the Val- ium or control conditions (Jay et al. A similar follow-up RCT by these researchers revealed identical effects on pain and arousal whether patients received a psychological intervention alone or in combination with Valium (Jay et al. Results indicated that general anesthesia was associated with less procedural distress, but no dif- ferences between interventions were observed regarding self-ratings of pain provided postprocedure. Subjects, all of whom received both types of pain intervention in the within-subject design, did not indicate a significant preference for one versus the other type of intervention, and it was noted that the psychological intervention required less time (Jay et al. As a whole, results of these well-controlled studies indicate that psychological interventions are of at least comparable efficacy to standard pharmacologi- cal approaches for management of the pain associated with bone-marrow aspiration in children.
