Pneumoperitoneum--a rare complication of cardiopulmonary resuscitation

Pneumoperitoneum following cardiopulmonary resuscitation: An unusual case

Introduction and importance

High-quality cardiopulmonary resuscitation (CPR) is the foundation of cardiac arrest resuscitation. Pneumoperitoneum due to gastric perforation is a rare surgical complication of CPR that, if left untreated, can result in significant morbidity and mortality.

Case presentation

We present a 51-year-old male patient with sealed perforation who received an urgent but non-diagnostic exploratory laparotomy after initial esophageal intubation and resuscitation in cardiac arrest, despite significant evidence of surgical pneumoperitoneum.

Clinical discussion

It is unusual to experience spontaneous pneumoperitoneum after cardiopulmonary resuscitation. We should promote cardiopulmonary resuscitation training for both medical and non-medical personnel.

Conclusion

Early endotracheal intubation, avoidance of esophageal intubation, and quick insertion of an orogastric tube may reduce the risk of gastric perforation.

Diaphragmatic rupture and massive pneumoperitoneum after cardiopulmonary resuscitation

Introduction:

Although cardiopulmonary resuscitation is an emergency life-saving procedure, the intervention itself can cause major and often fatal injuries, with diaphragmatic rupture being very rare. This report describes a patient who experienced bilateral pneumothoraces, left diaphragmatic rupture, and pneumoperitoneum after extended cardiopulmonary resuscitation.

Case presentation:

A 90-year-old woman experienced a cardiac arrest. Spontaneous circulation was restored after 49 min of cardiopulmonary resuscitation performed by a bystander, emergency medical service providers, and emergency department staff. Imaging showed bilateral pneumothoraces, left diaphragmatic rupture, and massive pneumoperitoneum. The patient’s guardian refused to permit surgery for the diaphragmatic rupture, and the patient died despite chest and abdominal decompression and post-cardiac arrest care.

Discussion and conclusion:

Procedures to restore spontaneous circulation in patients experiencing cardiac arrest may result in fatal cardiopulmonary resuscitation–related injuries. Clinicians providing post-cardiac arrest care should plan management for these iatrogenic injuries.

Stomach perforation post cardiopulmonary resuscitation-A case report

•

Stomach perforation after cardiopulmonary resuscitation is rare.

•

CPR performed by non-medical personnel is the main cause.

•

Training of medical and non-medical persons in CPR is to be encouraged.

•

Correct management of airway during CPR is important.

•

High degree of vigilance is required in patients presenting after CPR.

Introduction

Stomach perforation after cardiopulmonary resuscitation is a rare finding. This is mainly caused by incorrect management of the airway during CPR performed by non-medical personnel.

Presentation of case

We report a case of 72 year old female who sustained a stomach perforation during prolonged CPR in an out of hospital arrest situation. This was diagnosed on a computed tomography scan of the abdomen requiring midline laparotomy and a primary repair of the stomach.

Discussion

The training of medical and non-medical persons in cardiopulmonary resuscitation is to be encouraged. However it should be emphasized that any technique which breaches the normal integrity of the body can itself lead to life-threatening complications.

Conclusion

A high degree of vigilance is required in patients presenting after a cardiac arrest and CPR.

Do resuscitation-related injuries kill infants and children?

Occasionally, individuals accused of inflicting fatal injuries on infants and young children will claim some variant of the "CPR defense," that is, they attribute the cause of injuries found at autopsy to their "untrained" resuscitative efforts. A 10-year (1994-2003) historical fixed cohort study of all pediatric forensic autopsies at the Miami-Dade County Medical Examiner Department was undertaken. To be eligible for inclusion in the study, children had to have died of atraumatic causes, with or without resuscitative efforts (N(atraumatic) = 546). Of these, 382 had a history of cardiopulmonary resuscitation (CPR; average age of 4.17 years); 248 had CPR provided by trained individuals only; 133 had CPR provided by both trained and untrained individuals; 1 had CPR provided by untrained individuals only. There was no overlap between these 3 distinct groups. Twenty-two findings potentially attributable to CPR were identified in 19:15 cases of orofacial injuries compatible with attempted endotracheal intubation; 4 cases with focal pulmonary parenchymal hemorrhage; 1 case with prominent anterior mediastinal emphysema; and 2 cases with anterior chest abrasions. There were no significant hollow or solid thoracoabdominal organ injuries. There were no rib fractures. The estimated relative risk of injury subsequent to resuscitation was not statistically different between the subset of decedents whose resuscitative attempts were made by trained individuals only, and the subset who received CPR from both trained and untrained individuals. In the single case of CPR application by an untrained individual only, no injuries resulted. The remaining 164 children dying from nontraumatic causes and who did not undergo resuscitative efforts served as a control group; no injuries were identified. This study indicates that in the pediatric population, injuries secondary to resuscitative efforts are infrequent or rare, pathophysiologically inconsequential, and predominantly orofacial in location. In our population, CPR did not result in any rib fractures or significant visceral injuries. Participation of nonmedical or untrained individuals in resuscitation did not increase the likelihood of injury.

Gastric perforation after cardiopulmonary resuscitation: review of the literature

The risk of complications of cardiopulmonary resuscitation (CPR) does not outweigh the benefit of a successful restoration of a spontaneous circulation. Despite the frequent occurrence of gastric distension (caused by air entering the stomach because of too forceful and/or too quick rescue breathing), there are few reports of massive gastric distension causing gastric rupture and pneumoperitoneum after CPR. We reviewed all 67 case reports of gastric perforation that have been reported after CPR. Although uncommon, this review stresses the need to consider this potentially lethal complication after initial successful resuscitation.

Frequent and rare complications of resuscitation attempts

INTRODUCTION

Resuscitation attempts require invasive iatrogenic manipulations on the patient. On the one hand, these measures are essential for survival, but on the other hand can damage the patient and thus contain a significant violation risk of both medical and forensic relevance for the patient and the physician. We differentiate between frequent and rare resuscitation-related injuries. Factors of influence are duration and intensity of the resuscitation attempts, sex and age of the patient as well as an anticoagulant medication.

MATERIALS AND METHODS

Review of current literature and report on autopsy cases from our institute (approximately 1,000 autopsies per year).

RESULTS

Frequent findings are lesions of tracheal structures and bony chest fractures. Rare injuries are lesions of pleura, pericardium, myocardium and other internal organs as well as vessels, intubation-related damages of neural and cartilaginous structures in the larynx and perforations of abdominal organs such as liver, stomach and spleen.

CONCLUSION

We differentiate between frequent and rare complications. The risk of iatrogenic CPR-related trauma is even present with adequate execution of CPR measures and should not question the employment of proven medical techniques.

Benign pneumoperitoneum associated with pneumomediastinum and pneumoretroperitoneum in ambulatory outpatients

Perforation of a hollow viscus and other dangerous etiologies must always be considered in the evaluation of free peritoneal air. Pneumoperitoneum in the presence of pneumoretroperitoneum and pneumomediastinum, however, often results from air tracking from a pathologic source outside of the abdomen along the mesentery into the peritoneum. This syndrome is relatively benign, and should be considered when there are multiple sites of extraluminal air in order to minimize the risk of unnecessary exploratory laparotomy. Two cases of benign pneumoperitoneum associated with pneumomediastinum and pneumoretroperitoneum are presented.

Liver rupture after cardiopulmonary resuscitation in a patient receiving thrombolytic therapy

A patient with an acute myocardial infarction had to be resuscitated due to recurring ventricular fibrillation. After stabilisation, she received thrombolytic treatment with anistreplase. Fourteen hours later, clinical signs of hemoperitoneum developed and the diagnosis of liver rupture was made. After abdominal surgery and coronary revascularisation, the subsequent clinical course was uncomplicated. The literature on liver trauma after CPR as well as thrombolysis in association with CPR is reviewed. This observation suggests that there are no convincing arguments to withhold thrombolytic therapy in acute myocardial infarction after CPR in the absence of gross trauma. We stress that a high degree of clinical alertness is necessary to diagnose this life-threatening condition because of its frequent subacute evolution in patients that are per se hemodynamically unstable.

Rupture of the stomach caused by manual ventilation during laryngospasm

We report a case, in which laryngospasm developed due to a failed intubation under sedation. During ventilation tension pneumoperitoneum developed resulting in cardiac and respiratory failure. Laparotomy revealed two tears on the lesser curvature of the stomach. Factors influencing stomach rupture are discussed.

Pre-hospital cardiopulmonary resuscitation and pneumoperitoneum

A case is reported of pneumoperitoneum after prolonged ventilation of a smoke inhalation victim at the scene by a fireman using intermittent positive pressure ventilation. The clinical presentation, treatment and aetiology, when associated with cardiopulmonary resuscitation, are discussed. The need for adequate training in the use of resuscitation equipment is emphasized, especially for non-medical staff.

Tension pneumoperitoneum as an early complication after adenotonsillectomy

Pneumoperitoneum as a result of pneumomediastinum has been described already. Amongst the causes pneumoperitoneum due to a complication of adenotonsillectomy, has not previously been described. We describe a five-year-old girl with tension pneumoperitoneum with respiratory and circulatory insufficiency half an hour after adenotonsillectomy. Removal of the intra-abdominal air with a 14 gauge needle restored normal respiration and circulation.

Unexplained pneumoperitoneum in association with basic cardiopulmonary resuscitation efforts

During the mouth to mouth ventilation of basic life support, the high inflation pressures generated may result in later complications. Pulmonary barotrauma may result in pneumothorax or pneumomediastinum, and high pressures applied to the gastrointestinal tract may lead to gastric rupture and pneumoperitoneum. A case is reported of pneumoperitoneum in the absence of pneumothorax, pneumomediastinum or gastrointestinal perforation and the literature relating to this unusual condition is reviewed.
