[Prehospital chest tube placement: Which factors are associated with feeling confident to perform the procedure?] / Prähospitale Anlage von Thoraxdrainagen: Welche Faktoren sind mit einem subjektivem Sicherheitsgefühl assoziiert?

BACKGROUND: The prehospital placement of chest tubes is a rare but potentially life-saving procedure. A high level of subjective confidence with the procedure is essential for emergency medical doctors. This study aims to identify if there is a statistically significant difference in the subjective sense of confidence in prehospital chest tube placement regarding medical experience and qualification, clinical routine, and attendance at simulation courses. METHODS: Prehospital emergency physicians of three emergency medical services in Southwest Saxony, Greifswald, and Vechta, Germany, were invited to participate in an online survey from January to March 2022 using the online survey service limesurvey. The question "Do you feel confident in chest tube placement?" was used to measure the subjective level of confidence. Answers were compared with data concerning medical qualification, experience in prehospital emergency medicine, clinical routine, and attendance at simulation courses. Statistical analysis was performed using chi-squared test and Fisher's exact test. RESULTS: Three out of four participants felt confident in chest tube placement (53/71; 74.6%). More than half of the participants reported that they did not perform this procedure regularly (35/53, 66%). Subjective confidence was highest in physicians who regularly place chest tubes during their non-prehospital work (34/37; 91,9%; p<0.001), and more often when participants had clinical routine and attended simulation courses than when none of this applied (p=0.012). Attendance at simulation courses alone was not associated with a higher level of confidence (p=0.002). Specialists showed significantly more often subjective confidence in chest tube placement (p=0.0401). CONCLUSION: Prehospital chest tube placement is rare, but potentially lifesaving. An adequately high level of subjective confidence in the placement of chest tubes is a key condition for prehospital emergency doctors. Inhospital clinical routine and attendance at simulation courses are significantly associated with high levels of confidence. Our data indicate that working only in prehospital emergency settings without further clinical routine or medical specialization is not sufficient for achieving and ensuring subjective confidence in chest tube placement.

[Safety aspects of prehospital thoracic emergency procedures: Results of a survey among German emergency physicians]. / Sicherheitsaspekte invasiver thorakaler Maßnahmen in der prähospitalen Notfallmedizin ­ Ergebnisse einer Umfrage unter deutschen Notärzt:innen.

BACKGROUND: The safe indication and performance of thoracic emergency procedures are crucial and potentially lifesaving in prehospital emergency care. This study aims to investigate issues of patient safety and quality assurance of prehospital invasive thoracic interventions. The survey does not represent the actual medical care situation but explores reasons for security concerns among emergency physicians. METHODS: Using a pre-validated questionnaire, prehospital emergency physicians of three prehospital rescue associations (Zweckverband) in Southwest Saxony, Greifswald, and Vechta, Germany, were queried via the online survey service limesurvey. The survey was conducted between January and March 2022. RESULTS: 104 emergency physicians participated (response rate 42.4%) 71 of which fully completed the survey (68%). 79% of the participants stated that they felt safe in performing pleural punction. Common reasons for postponing prehospital thoracic interventions included fear of complications or individual patient characteristics. 90% said that they were familiar with the on-board equipment options, and 60% reported that resources were sufficient to perform double-sided procedures. While in all three regions there is sufficient on-board equipment to perform procedures on two sides, one out of two participants said that lack of equipment deters them from performing prehospital invasive thoracic procedures. Emergency physicians who graduated from trauma courses and/or participate in air rescue are more likely to perform invasive thoracic procedures. More than half of the participants wanted more training in chest tube placement or pleural punction. CONCLUSION: Safety in prehospital invasive thoracic procedures needs improvement in structural, procedural, as well as human factors aspects. Safe handling of these rare but vital techniques requires more training. A lack of knowledge of equipment is a significant safety gap. Prehospital ultrasound constitutes a structural element of prehospital diagnostics.

[Outpatient Management of Primary Spontaneous Pneumothorax]. / Ambulantes Management des primären Spontanpneumothorax.

Outpatient Management of Primary Spontaneous Pneumothorax Abstract. Pneumothorax (PT) is defined as a collapse of the lung due to the collection of air in the pleural space. In primary spontaneous pneumothorax (PSP) there is no underlying pulmonary pathology. Treatment, either conservative or invasive, depends on the size of the PT, the patient's clinical situation and the patient's setting/environment. According to the actual literature, the uncomplicated PSP can at best be treated conservatively and on an outpatient basis. Management with intervention (needle aspiration or chest drainage) is historically carried out on an inpatient basis, but outpatient management (without comorbidities and without symptoms) is also possible. In these cases, the patient compliance (motivation, cognition, support, housing situation …) has to be proven. For outpatient management with intervention, a small-caliber chest tube (<14 F) with a Heimlich valve should be used.
