Use of ultrasound guidance in central venous catheter placement by emergency physicians in Saudi Arabia.

OBJECTIVES: To determine the ultrasound guidance for central venous catheter (USG-CVC) placement rate of emergency physicians (EPs) in Kingdom of Saudi Arabia. METHODS: A cross-sectional survey study regarding the respondents' demographic profiles, formal and informal training in USG-CVC placement, experiences, and attitudes towards the procedure was emailed to all EPs registered with the Saudi Commission for Health Specialties (SCFHS) between October and December 2018. RESULTS: In total, 234/350 SCFHS-registered EPs completed the survey; the response rate was 66.9%. Most respondents (70.5%) were board-certified in emergency medicine (EM). Ninety percent indicated that US device for CVC placement assistance was available. Most EPs (78.2%) had performed USG-CVC placement; the US usage rate correlated significantly with recent graduation from residency (p=0.048). In total, 83.3% received formal training during residency. Of the 234 respondents, 53.8% felt extremely comfortable with CVC placement with USG and 19.7% without USG (p less than 0.01). Nevertheless, most respondents desired further USG-CVC training. CONCLUSION: Despite existing evidence and a consensus on its superiority over the landmark technique, USG-CVC placement has not been adopted by a small proportion of EPs into clinical practice. Formal training, education, and institutional provision of permanent onsite US machines may address any barriers.

Use of noninvasive positive pressure ventilation during pregnancy: case series.

Mechanical ventilation is commonly required in critically ill pregnant patients, requiring ICU admission, with higher morbidity and mortality related to airway management. Alternatively, noninvasive positive pressure ventilation (NIPPV) is increasingly used to treat nonpregnant patients. Pregnancy has been a contraindication to its use. We would like to report a case series of successful use of NIPPV in pregnancy.NIPPV is increasingly used to treat hypoxemic respiratory failure. It has rarely been used during pregnancy. On the other hand, acute respiratory failure (ARF) remains a leading cause of ICU admission in obstetric patients. The use of NIPPV in managing ARF in pregnant patients was not investigated. We report the outcome of treatment with NIPPV of four sickle cell disease pregnant patients with ARF caused by acute chest syndrome. Median APACHE II score for the four cases was 27. Intubation was avoided in all cases. None had aspiration. Mean duration of NIPPV was 40 h with ICU discharge after a mean of 4 days.

Pulmonary hydatid cyst in a pregnant patient causing acute respiratory failure.

A 21-year-old primigravida, at 32 weeks of gestation, presented with acute onset of respiratory failure and circulatory shock. Chest imaging showed findings suggestive of ruptured hydatid cyst, which was confirmed by histology post-thoracotomy. Tissue cultures from the removed cyst grew Mycobacterium tuberculosis also. She was successfully managed in the intensive care unit and was then discharged home on antituberculosis medications in addition to albendazole after prolonged hospitalization and a need for chest tube for bronchopleural fistula. Acute respiratory failure and anaphylactic shock secondary to ruptured pulmonary hydatid cyst and superimposed pulmonary tuberculosis in a pregnant lady should be considered in patients living in endemic areas.

Successful use of non-invasive positive pressure ventilation in a complicated flail chest.

The current advanced trauma life support manual states that patients with significant hypoxia namely, SaO2 <90% on room air as a result of pulmonary contusion should be intubated and ventilated within the first hour of injury. Recently, several researchers have shown improved outcomes when patients with acute respiratory failure are managed with non-invasive positive pressure ventilation NIPPV. Trauma patients may also benefit from this therapy. We report a case of 15-year-old boy with isolated flail chest and pulmonary contusion, who was intubated in the emergency room, and was managed successfully with the NIPPV in the intensive care unit ICU despite, having had aspiration pneumonia early in the course of his stay. After initial stabilization, he failed a spontaneous breathing trial. Due to absence of contraindications to the use of NIPPV, the patient was extubated on day 7 from pressure support ventilation of 15 cmH2O and positive end expiratory pressure of 8 cmH2O to immediate NIPPV use. Three days later after a total of 50 hours of NIPPV use in the ICU the patient was successfully discharged home.

Clinical review: percutaneous dilatational tracheostomy.

As the number of critically ill patients requiring tracheotomy for prolonged ventilation has increased, the demand for a procedural alternative to the surgical tracheostomy (ST) has also emerged. Since its introduction, percutaneous dilatational tracheostomies (PDT) have gained increasing popularity. The most commonly cited advantages are the ease of the familiar technique and the ability to perform the procedure at the bedside. It is now considered a viable alternative to (ST) in the intensive care unit. Evaluation of PDT procedural modifications will require evaluation in randomized clinical trials. Regardless of the PDT technique, meticulous preoperative and postoperative management are necessary to maintain the excellent safety record of PDT.
