Spleen-saving procedures in paediatric splenic trauma

The aim of this study is to assess the advantages of 'spleen-saving procedures' in paediatric splenic trauma. Since January 1979, 87 children with splenic trauma were treated. Six were treated without operation. Eighty-one patients were treated surgically. Sixteen cases with type I splenic injury were subject to simple splenorrhaphy, and twenty-three cases with type II splenic injury underwent splenorrhaphy plus omentoplasty. Twenty-four cases had type III splenic injury; of these, 20 were treated by ligation of the splenic artery (the main splenic artery in 14 cases and the upper segmental artery in six cases) with splenorrhaphy and omentoplasty, and the remaining four cases were treated by partial splenectomy and omentoplasty. In 16 of the 18 patients with type IV splenic injury, splenectomy was inevitable and heterotopic splenic autotransplantation was added. In the remaining two cases, it was possible partially to preserve the spleen. No complication was observed due to any of these spleen-saving procedures. Moreover, splenic implants increased complement C3 levels and improved filtration function. Despite other injuries, the mortality rate of this group was 5.7 per cent. The splenic salvage rate was 82 per cent.     

Assessing outcomes in paediatric trauma populations

INTRODUCTION: Assessing outcomes in the paediatric trauma population is important. Identifying suitable instruments can be problematic. This article highlights the commonly used outcome measures for assessing functional status and health related quality of life in paediatric trauma patients. Child specific characteristics which impact upon instrument development and selection are reviewed. METHODS: An electronic database search was conducted to identify suitable English language measures used for outcome assessment in paediatric trauma patients from 1966 to present. RESULTS: Nine suitable instruments were identified, the child health questionnaire (CHQ), Glasgow outcome scale (GOS), paediatric overall performance category (POPC), PedsQL 4.0 generic core scales, paediatric evaluation of disability inventory (PEDI), functional independence measure (FIM), WeeFIM and an unnamed paediatric trauma specific measure [Gofin R, Hass T, Adler B, The development of disability scales for childhood and adolescent injuries. J Clin Epidemiol 1995;48:977-84]. Each instrument was found to have advantages and disadvantages for assessing outcomes in a paediatric trauma population. CONCLUSION: The PedsQL 4.0 generic core scale could be feasible for administration as a routine outcome measure for paediatric trauma groups. For very young children an additional measure such as that proposed by Gofin et al. [Gofin R, Hass T, Adler B, The development of disability scales for childhood and adolescent injuries. J Clin Epidemiol 1995;48:977-84] may be indicated. Future use of these instruments in the paediatric population would benefit from further psychometric evaluation.     

Ionising radiation exposure in paediatric trauma

Introduction

Trauma remains the highest cause of paediatric morbidity and mortality. These trauma patients incur radiation exposure during intraoperative management. Medical personnel have the responsibility to ensure observation of the ‘as low as reasonably achievable’ principle, a practice mandate that minimises ionising radiation exposure. The aim of this study was to quantify the difference in the amount of ionising radiation used by operating surgeons of different grades in paediatric trauma surgery.

Methods

Intraoperative imaging in paediatric trauma surgery between 2008 and 2010 at a UK trauma centre was analysed retrospectively, recording injury demographics, surgeon grade, radiation exposure (dose area product [DAP]) and screening time. A mobile image intensifier was used in all cases and the lowest dose rate was selected for all screening.

Results

A total of 782 trauma cases were analysed: 304 procedures (39%) were carried out by consultants, 127 (16%) by senior registrars and 351 (45%) by junior registrars. The mean screening time for consultants was 0.23 minutes (standard deviation [SD]: 0.21 minutes) while for senior registrars it was 0.24 minutes (SD: 0.27 minutes) and for junior registrars 0.47 minutes (SD: 1.5 minutes). The mean DAP for consultants was 58.49Gycm² (SD: 53.66Gycm²). For senior registrars it was 87.2Gycm² (SD: 126.64Gycm²) and for junior registrars it was 90.46Gycm² (SD: 180.02Gycm²). This equates to a 51% increase in screening time and a 35% increase in DAP by a junior registrar compared with a consultant.

Conclusions

Significantly lower screening times and radiation exposure was found in procedures performed by consultants compared with registrars (p<0.001). Given the harmful and unknown long-term effects of ionising radiation exposure in children, we recommend increasing consultant presence in paediatric trauma theatres.     

Treatment of splenic trauma in paediatric age

The splenic trauma in children presents some peculiarity that differentiates it from that one in adult age. Therefore we have see again our relative experience on splenic trauma, in the period 2001-2006, confronting two groups of patients, one of inferior age to fourteen years (A Group) and one of advanced age (B Group). We have estimated the following parameters: aetiology, type of lesion, association with others trauma, type of treatment, compliance, mortality, number of transfusions and hospital stay. On a total of 75 splenic trauma (M:52, F:23 of age comprised between 5 and 71 years) 18 belongs to the A group (medium age of 9.2 years) and 57 to the B group (medium ages of 47.4 years). The prevailing aetiology in the A group is domestic accident (39%) and the fall from bicycle (33%), while in the B group it is the street accident (69%). The lesions found in pediatric age are of smaller gravity if compared with B group, for lesion gravity and for association with abdominal and/or extra-abdominal others trauma. In the children group we have performed nonoperative management or conservative surgery in the 83% of cases versus the 26% in the B group. The rate of conversion from a nonoperative treatment in to an operative treatment has been of 7%. The post-operative complicance are absent in the A group and of 5.5% in the B group. The mortality rate in the surgical patients has been of the 14.3% for serious toraco-abdominal trauma in A group and of 11.1% in B group. No mortality is detected in the groups with nonoperative treatment. The medium number of transfusions is of 1.8 units in the paediatric patients and of 2.5 units in the adults. The medium stay in hospital is of eighteen days in the A group and of thirteen days in the B group. In conclusion the marked difference in the two groups examines stays in the type of treatment, more often nonoperative or conservative in the children group.     

Popliteal vasculature injuries in paediatric trauma patients

Popliteal-artery injuries in the paediatric-trauma patient are uncommon, difficult to diagnose and with prolonged ischaemia lead to substantial complications. We report three cases of popliteal-vasculature injury in paediatric-trauma patients with diverse mechanisms of injury: blunt trauma, penetrating injury and a Salter-Harris I fracture. We present a range of the significant sequelae that can result from paediatric popliteal-artery injury, both physically and psychologically. It is imperative that clinicians have a high index of suspicion when confronted with paediatric patients with trauma around the knee and that popliteal-vasculature injuries are diagnosed early. If insufficiencies are detected, further imaging should be considered, but surgical exploration should not be delayed in the presence of ischaemia.     

Blunt abdominal aortic trauma in paediatric patients

Background

Blunt abdominal aortic trauma (BAAT) is a very rare occurrence in children, with significant morbidity and mortality. Varied clinical presentations and sparse literature evidence make it difficult to define the proper management policy for paediatric patients.

Method

We report our centre's data on three consecutive children with BAAT managed between 2006 and 2010. A Medline search was also performed for relevant publications since 1966, together with a review of references in retrieved publications.

Results

Forty children (range 1–16 years) were included in our final analysis. Motor vehicle crashes (MVC) were the leading cause of injury (65%). The in-hospital mortality rate was 7.5% (3/40). Nine patients (22.5%) ended up with residual sequelae. Main primary aortic lesions were complete wall rupture (12.5%), intimal transection (70%) and pseudoaneurysm (15%). Twenty-eight children underwent aortic surgical repair (70%). Among the 12 non-operatively managed patients, 41.6% had complications, including one death.

Conclusion

Symptomatic lesions and complete ruptures should undergo immediate surgical repair. Circumferential intimal transections are at high risk of complication and should also receive intervention. Partial intimal transections and delayed pseudoaneurysms can be initially observed by clinical examination and imaging. Patients with these latter pathologies should be operated on at any sign of deterioration.     

Pre-hospital trauma care

The chain of survival in outcome from major trauma is equally as important as its well established concept in survival from cardiac arrest. Preventive measures have been shown to be an effective means of reducing death from trauma, and the standard of pre-hospital care for those surviving the primary injury is improving in many trauma systems. The optimal pre-hospital interventions are still debated, but evidence suggests that patients with severe head injury in particular will benefit significantly from pre-hospital rapid-sequence intubation and field stabilization, whereas those with penetrating injury require rapid evacuation to hospital with minimal intervention. Pre-hospital asystole from trauma has a universally poor outcome. When delivering appropriate care, several helicopter-based systems have shown improvements in outcome compared with ground-based systems. The International Liaison Committee on Resuscitation recently published guidelines on resuscitation, with particular relevance to pre-hospital trauma care. The importance of bystander cardiopulmonary resuscitation, oxygenation, and the avoidance of iatrogenic morbidity are stressed.     

The use of upper limb external fixation in paediatric trauma

External fixation is an alternative method of treatment for paediatric fractures of the upper extremity. We report our experience of the management of 23 children with an average age of 10 years 1 month and review the literature. The method is indicated for second and third degree open fractures, open multiply injured patients and severely comminuted fractures. External fixation has proved unequalled for correction of limb deformities and lengthening procedures.     

Nasal ketamine for paediatric premedication

Ketamine in a dose of 6 mg · kg⁻¹ was nasally administered in 86 healthy children (ASA I and II), aged from two to five years undergoing elective general, urological or plastic surgery, 20 to 40 min before the scheduled surgery time. These children were compared with 62 others, also aged from two to five years, in whom promethazine and meperidine, 1 mg · kg⁻¹ of each, were injected im. Sedation was started as excellent in 48 and as adequate in 19 children in the ketamine group, compared with nine and 12 respectively in Group 2 (P < 0.05), while salivation was similar in both groups. We conclude that nasal ketamine is an alternative to im preanaesthetic sedation administration in children aged from two to five years. Vingt à quarante minutes avant la chirurgie, de la kétamine 6 mg · kg⁻¹ est administrée par voie nasale à 86 enfants en bonne santé (ASA I et II), agés de deux à cinq ans programmés pour une intervention urologique ou plastique non urgente sous anesthésie générale. On compare ces enfants à 62 autres enfants du même age, auxquels on a injecté par la voie i.m., soit de la mépéridine, soit de la prométhazine, à la dose de 1 mg · kg⁻¹. La sédation est jugée excellente pour 48 et adéquate pour 19 des enfants du groupe kétamine, comparativement à 9 et 12 des enfants du groupe 2 (P < 0,05), alors que la salivation est identique dans les deux groupes. Nous en concluons que la kétamine nasale est une alternative a la prémédication intramusculaire pour des enfants de deux à cinq ans.     

Intranasal ketamine preinduction of paediatric outpatients

A double-blinded, placebo-controlled study compared the outcomes of intranasal ketamine premedication with placebo in outpatients. Forty paediatric outpatients were assigned randomly in a prospective fashion to one of two separate study groups of equal size (20 patients per group). A placebo group received 2 ml of intranasal saline, 1 ml per naris. The study group received intranasal ketamine, 3 mg·kg⁻¹, diluted to 2 ml with saline, 1 ml per naris. Using a cooperation index, a play therapist scored resistance to nasal instillation, separation of the child from parents at ten min, and acceptance of anaesthesia monitors and face mask at 15 min. Differences in age, weight, episodes of vomiting, recovery and discharge times among the two groups were not significant. Intranasal ketamine, 3 mg·kg⁻¹, was asssociated with a significantly better ( P =0.013) cooperation index than intranasal placebo. Intranasal ketamine, permitted pleasant and rapid separation of children from their parents, cooperative acceptance of monitoring and of mask inhalation induction, and did not cause prolonged postanaesthetic recovery or delayed discharge home.     

Pre-hospital trauma care: systems and delivery

The first 150 words of the full text of this article appear below. Key points Victims of trauma often spend a significant periodof time in the pre-hospital phase. There is wide variationin the practice of pre-hospital care internationally. The term‘paramedic’ covers a wide range of skills and abilities. Incountries other than the UK, physician-led pre-hospital careis well established. Where pre-hospital anaesthesia is performed,in-hospital standards should apply.   When the literature on pre-hospital trauma care is examined,it becomes apparent that a significant period of time is oftenspent between the time of accident and arrival in the emergencydepartment. Although the ‘Golden Hour’ is an arbitraryconcept, it is often applied to trauma care and emphasizes theimportance of life-saving interventions soon after injury. Inthe UK and elsewhere, the majority of the first hour has passedbefore the hospital-based physician has contact with the patient.Time at the scene can be much longer if the patient is . . .
