A Retrospective Analysis of Needle Thoracostomies at a Tertiary Level 2 Trauma Center

BACKGROUND

A tension pneumothorax is a condition that results in elevated pressure within the pleural space. The effective management of tension pneumothorax relies on needle decompression, commonly performed at the second intercostal space (ICS) midclavicular line (MCL). However, some literature suggests that catheters placed in the second intercostal space midclavicular line are prone to higher failure rates compared to the fifth intercostal space midaxillary line (MAL) (42.5% versus 16.7%, respectively). In this study, we aim to identify and scrutinize the prevalence of prehospital needle decompression from one tertiary care center over eight years and examine their trends, efficacies, or pitfalls. It is hypothesized that preclinical providers are performing needle decompression prematurely and unnecessarily.

METHODS

A set of 90 patient records obtained using the trauma registry at Saint Francis Hospital, Tulsa, Oklahoma, were retrospectively reviewed to evaluate the management and outcomes of tension pneumothorax, as well as the indications documented for needle decompression. Patient charts were reviewed via Epic Hyperspace (Epic, Madison, WI). The Oklahoma Emergency Medical Service Information System (OKEMSIS) also provided information contributing to the sample population.

RESULTS

The most documented indications for needle decompressions included diminished or absent breath sounds (52.70%), hypoxia (15.54%), hypotension, and hemodynamic instability (6.76%). Emergency medical services (EMS) reported improvements in 51 (56.67%) patients after needle thoracostomy. Improvements in vital signs after needle decompression were sporadic. The most common complication was catheter dislodging, which occurred most in the second intercostal space midclavicular line. Only nine patients had an oxygen saturation (SpO2) below 92% and a systolic blood pressure (SBP) below 100 mm Hg prior to receiving needle decompression.

CONCLUSION

Current practices for tension pneumothorax show little improvement in vital signs before and after needle decompression. Vital signs prior to needle decompression often do not indicate tension pneumothorax physiology. Preclinical providers may be inappropriately performing needle decompressions, an invasive procedure with complications.

Pneumoperitoneum After Jejunostomy Tube Placement Managed by Needle Decompression: A Case Report

Percutaneous endoscopic feeding tube placement is a commonly performed procedure in patients who cannot take food by mouth. While it is considered a safe and effective method of providing nutritional support, like any medical procedure, it can lead to complications. Feeding tube placement, including percutaneous endoscopic jejunostomy (PEJ), is associated with several complications, including bleeding, site infection, aspiration, buried bumper, tube dislodgement, and pneumoperitoneum. We report a case of a 20-year-old male with multiple medical issues who underwent a PEJ that was complicated by bowel distension. The patient developed tension pneumoperitoneum post-procedure, which was treated with a bedside needle decompression. This case report highlights the significance of promptly recognizing and intervening in complications that may arise during a frequently performed medical procedure, PEJ tube placement, to prevent serious consequences, including bowel ischemia.

Needle Decompression Causing Pericardial and Pulmonary Artery Injuries in Patients With Blunt Trauma: Two Case Reports and Literature Review

Tension pneumothorax (TPX) is a severe chest complication of blunt or penetrating trauma. Immediate decompression is the lifesaving action in patients with TPX. Needle decompression (ND) is frequently used for this purpose, particularly in limited resources setting such as the prehospital arena. Despite the safe profile, the blind nature of the procedure can result in a serious range of complications, including injury to the vital intrathoracic structures such as the lungs, great vessels, and heart. Here, we reported 2 cases of blunt chest trauma resulting in TPX demanding immediate ND; however, nonintentional pericardial and pulmonary artery injuries occurred. The first case was a 42-year-old man with a needle-related pulmonary artery injury that required surgery. The second case was a 19-year-old man in whom a needle-related pneumopericardium occurred and was treated conservatively. In both cases, trained personnel performed the ND. Although ND in the field is a lifesaving intervention, it may further complicate the patient condition. Therefore, it should be performed in adherence to the universal guidelines.

Anatomic and physiologic approach for trans-conjunctival needle decompression of orbital emphysema

A 19-year-old with blunt trauma and repeated nose blowing presented with orbital emphysema and orbital compartment syndrome. Orbital emphysema is the abnormal presence of air within the orbit, typically secondary to trauma. Most cases will resolve with observation alone, however orbital compartment syndrome is a feared complication that necessitates urgent decompression. A superior fornix, trans-conjunctival approach was safely utilized to decompress the orbit while avoiding unwanted complications. Various decompression techniques have previously been described, most of which describe trans-palpebral approaches. The key safety benefit to the trans-conjunctival approach is direct visualization of the needle tip adjacent to the superior fornix, therefore posterior to the equator of the globe. With the needle positioned parallel to the curvature of the globe at the equator, the posterior sclera surface curves away from the tip, rendering it difficult to pierce the globe. In addition, the needle needs to be advanced only 3-4 millimeters and traverses only the conjunctiva and Tenon's to enter the central surgical space - the most direct route to the air pocket. The trans-conjunctival approach lowers the risk of damage to eyelid neurovascular structures and is less painful.

Clinical Characteristics of Patients Undergoing Needle Thoracostomy in a Canadian Helicopter Emergency Medical Service

Objective: Needle thoracostomy (NT) can be a life-saving procedure when used to treat tension pneumothorax. However, there is some question regarding the efficacy of NT in the prehospital setting. Failure to treat tension pneumothorax in a helicopter emergency medical service (HEMS) setting may prove especially deleterious to the patient due to gas expansion with increasing altitude. This study's objective was to identify the characteristics of patients treated with NT in a Canadian HEMS setting and the factors that may influence outcomes following NT use.Methods: This was a retrospective chart review of prehospital records from a Canadian HEMS service. Patients aged 18 years and older who underwent at least one NT attempt using a 14-gauge 8.3 cm needle from 2012 to 2018 were identified. Charts were reviewed to collect demographic data, NT procedural characteristics, vital signs, and clinical response metrics. Descriptive statistics were used to characterize the study sample and overall event characteristics. Binary logistic regression was performed to identify variables associated with a clinical response to the initial NT treatment.Results: 163 patients (1.3%) of 12,407 patients attended received NT. A positive clinical response to NT was recorded in 37% (n = 77) of the total events (n = 208), the most common of which was an improvement in blood pressure (BP) (18.8%, n = 39). Initial NT was associated with a low likelihood of clinical improvement in patients presenting with blunt trauma (OR = 0.18; p = .021; 95% CI [.04, .77]), CPR prior to NT (OR = 0.14; p = .02; 95% CI [.03, .73]), or in those who received bilateral NT treatment (OR = 0.13; p < .01; 95% CI [.05, .37]). A pretreatment BP < 90 mmHg was predictive of a positive clinical response to initial NT (OR = 3.33; p = .04; 95% CI [1.09, 10.20]).Conclusions: Only a small portion of patients in the setting of a Canadian HEMS service were treated with NT. Patients most likely to receive NT were males who had suffered blunt trauma. NT may have questionable benefit for patients presenting with blunt trauma, in cardiac arrest, or requiring bilateral NT.

Needle decompression of the abdomen in a premature infant with abdominal compartment syndrome and cardiopulmonary arrest: A case report

A premature infant with abdominal compartment syndrome underwent cardiopulmonary arrest before receiving decompressive laparotomy, and the effect of cardiopulmonary resuscitation was poor. The abdomen was punctured with an 18-gauge needle, alleviating the distension and resulting in successful cardiopulmonary resuscitation.

The Nipple as a Landmark for Needle Decompression of Tension Pneumothorax in Children - A CT-Based Evaluation and Proposal of an Alternative Insertion Site

OBJECTIVE

Needle decompression of tension pneumothorax in children is a rarely encountered but potentially life-saving procedure, that is accompanied by a certain risk of injury. We evaluated the nipple as a landmark for an alternative anterior insertion site and as an aid in localizing lateral insertion sites, as well as its influence on the safety profile of the procedure.

METHODS

In thoracic computer tomography scans of children aged 0-10 years, the distance to the closest vital structure was compared between the traditional anterior insertion site (2nd intercostal space midclavicular line) and an alternative anterior insertion site (2nd intercostal space at the nipple line). Furthermore, the level of the nipple at the midaxillary line was investigated as guidance in quickly localizing the lateral insertion site and ensuring an insertion site high enough to avoid intraabdominal injury by the decompression needle. Additionally, correlation of these measures with age was investigated.

RESULTS

The distance to the closest vital structure at the 2nd intercostal space was significantly bigger at the nipple line compared to the midclavicular line (right: 2.23 ± 1.13 cm vs. 0.99 ± 0.80 cm, p < 0.0001; left: 1.92 ± 1.19 cm vs. 0.81 ± 0.70 cm, p < 0.0001). At the midaxillary line, the level of the nipple was at the 4th or 5th intercostal space in the majority of children (right: 83.8%; left: 88.1%). The mean distance from the nipple to the diaphragmatic cupola was 2.63 ± 1.85 cm on the right and 3.40 ± 1.86 cm on the left hemithorax.

CONCLUSION

When performing anterior needle decompression in children, we recommend inserting the needle at the more lateral insertion site at the 2nd intercostal space at the nipple line. At the lateral decompression sites, the nipple can be used as a marker for localizing the correct intercostal space for insertion and thereby ensuring enough caudad distance to the diaphragm to avoid abdominal injury.

Orbital emphysema after transcanalicular laser-assisted dacryocystorhinostomy treated with needle decompression

Orbital emphysema is an abnormal presence of air in the orbit. It usually arises after blunt trauma or periorbital surgery. When it occurs after dacryocystorhinostomy, usually it is reported as a benign condition. We present a case of a severe orbital emphysema secondary to transcanalicular diode laser-assisted dacryocystorhinostomy. The day after the surgery, the examination revealed crepitant periorbital swelling, general restriction of extraocular motility, visual loss and intraocular pressure of more than 70 mmHg. A computed tomography showed a massive orbital emphysema. An emergency decompression, using a 25-gauge needle attached to an empty syringe lacking a plunger was performed, achieving a quick decrease of intraocular pressure and pain and swelling improvement. Then, in this case, orbital decompression by passive airflow using a needle without a plunger was an effective treatment method to resolve a serious orbital emphysema after transcanalicular laser-assisted dacryocystorhinostomy.

Emergency Medical Services Simple Thoracostomy for Traumatic Cardiac Arrest: Postimplementation Experience in a Ground-based Suburban/Rural Emergency Medical Services Agency

BACKGROUND

Tube thoracostomy has long been the standard of care for treatment of tension pneumothorax in the hospital setting yet is uncommon in prehospital care apart from helicopter emergency medical services.

OBJECTIVE

We aimed to evaluate the performance of simple thoracostomy (ST) for patients with traumatic cardiac arrest and suspected tension pneumothorax.

METHODS

We conducted a retrospective case series of consecutive patients with traumatic cardiac arrest where simple thoracostomy was used during the resuscitation effort. Data were abstracted from our Zoll emergency medical record (Zoll Medical Corp., Chelmsford, MA) for patients who received the procedure between June 1, 2013 and July 1, 2017. We collected general descriptive characteristics, procedural success, presence of air or blood, and outcomes for each patient.

RESULTS

During the study period we performed ST on 57 patients. The mean age was 41 years old (range 15-81 years old) and 83% were male. Indications included 40 of 57 (70%) blunt trauma and 17 of 57 (30%) penetrating trauma. The presenting rhythm was pulseless electrical activity 65%, asystole 26%, ventricular tachycardia/fibrillation 4%, and nonrecorded 5%. Eighteen of 57 (32%) had air return, 14 of 57 (25%) return of spontaneous circulation, with 6 of 57 (11%) surviving to 24 h and 4 of 57 (7%) discharged from the hospital neurologically intact. Of the survivors, all were blunt trauma mechanism with initial rhythms of pulseless electrical activity. There were no reported medic injuries.

CONCLUSIONS

Our data show that properly trained paramedics in ground-based emergency medical services were able to safely and effectively perform ST in patients with traumatic cardiac arrest. We found a significant (32%) presence of pneumothorax in our sample, which supports previously reported high rates in this patient population.

Needle Decompression of Tension Pneumothorax with Colorimetric Capnography

BACKGROUND

The success of needle decompression for tension pneumothorax is variable, and there are no objective measures assessing effective decompression. Colorimetric capnography, which detects carbon dioxide present within the pleural space, may serve as a simple test to assess effective needle decompression.

METHODS

Three swine underwent traumatically induced tension pneumothorax (standard of care, n = 15; standard of care with needle capnography, n = 15). Needle thoracostomy was performed with an 8-cm angiocatheter. Similarly, decompression was performed with the addition of colorimetric capnography. Subjective operator assessment of decompression was recorded and compared with true decompression, using thoracoscopic visualization for both techniques. Areas under receiver operating curves were calculated and pairwise comparison was performed to assess statistical significance (P < .05).

RESULTS

The detection of decompression by needle colorimetric capnography was found to be 100% accurate (15 of 15 attempts), when compared with thoracoscopic assessment (true decompression). Furthermore, it accurately detected the lack of tension pneumothorax, that is, the absence of any pathologic/space-occupying lesion, in 100% of cases (10 of 10 attempts). Standard of care needle decompression was detected by operators in 9 of 15 attempts (60%) and was detected in 3 of 10 attempts when tension pneumothorax was not present (30%). True decompression, under direct visualization with thoracoscopy, occurred 15 of 15 times (100%) with capnography, and 12 of 15 times (80%) without capnography. Areas under receiver operating curves were 0.65 for standard of care and 1.0 for needle capnography (P = .002).

CONCLUSIONS

Needle decompression with colorimetric capnography provides a rapid, effective, and highly accurate method for eliminating operator bias for tension pneumothorax decompression. This may be useful for the treatment of this life-threatening condition.

Needle decompression in a patient with vision-threatening orbital emphysema

Orbital emphysema is a condition resulting from trapping of air in loose subcutaneous or orbital tissues from the paranasal sinuses. This condition commonly seen in patients with a history of periorbital trauma or surgery, especially following sneezing or nose blowing. It usually has a benign and self-limited course. However, the entrapped orbital air can cause a substantial increase in pressure with restricted ocular motility or vascular compromise and become severe enough to cause visual impairment. We herein present the case of a patient who developed severe orbital emphysema after blunt trauma followed by sneezing and was successfully treated with needle decompression of intraorbital air. Emergency needle decompression resulted in an improvement in vision and intraocular pressure.

Which method is more effective in treatment of calcific tendinitis in the shoulder? Prospective randomized comparison between ultrasound-guided needling and extracorporeal shock wave therapy

HYPOTHESIS

Ultrasound (US)-guided needling with subacromial corticosteroid injection is more effective than extracorporeal shock wave therapy (ESWT) for function restoration and pain relief in patients with calcific tendinitis of the shoulder.

METHODS

Fifty-four patients diagnosed with unilateral painful calcific tendinitis were randomly allocated to a US needling or ESWT group. The US needling group underwent US-guided needling and received a subacromial corticosteroid injection. The ESWT group received ESWT 3 times a week. All patients were prospectively evaluated; American Shoulder and Elbow Surgeons, Simple Shoulder Test, and visual analog scale for pain scores were recorded before the procedure and at 6 weeks, 12 weeks, 6 months, 12 months, and the last follow-up. The size and morphology of the deposits were evaluated by radiography.

RESULTS

The average follow-up period was 23.0 months. At last follow-up, the mean size of the deposits was significantly different between the 2 groups (P = .001); it decreased to 0.5 mm from 14.8 mm in the US needling group and to 5.6 mm from 11.0 mm in the ESWT group. There were also significant improvements in clinical outcomes in both groups after treatment (P < .05). At 1-year follow-up, the US needling group had significantly better scores than the ESWT group with regard to the American Shoulder and Elbow Surgeons assessment (90.3 and 74.6, respectively; P = .001), Simple Shoulder Test (83.3 and 70.8, respectively; P = .015), and visual analog scale for pain (1.4 and 3.3, respectively; P = .003).The initial calcium deposit sizes and clinical outcomes were weakly correlated in both groups (P > .05).

CONCLUSION

Both treatment modalities for calcific tendinitis improved clinical outcomes and eliminated calcium deposits. US-guided needling treatment, however, was more effective in function restoration and pain relief in the short term.

Tension pneumoperitoneum: a rare complication of upper gastrointestinal endoscopy

INTRODUCTION

Tension pneumoperitoneum is defined as the massive accumulation of air in the peritoneal cavity, which results in a sudden increase in intraabdominal pressure. Various iatrogenic procedures are responsible for this complication. We herein report a case of tension pneumoperitoneum resulting from upper gastrointestinal endoscopy.

CASE DESCRIPTION

A 45-y-old man was referred to our department because of melena. Esophagogastroscopy was unsuccessful because of failure to inflate the stomach, and sudden abdominal distension was noted immediately after the procedure. The hemodynamic status of the patient was compromised, and the imminent collapse was prevented with emergent needle paracentesis. Decompression of the abdominal cavity restored vital signs to normal allowing definitive surgical treatment.

DISCUSSION

Upper gastrointestinal endoscopy is a rare cause of this life-threatening complication. The combination of acute abdominal distension with hemodynamic instability following endoscopic procedures should raise suspicion of tension pneumoperitoneum. Needle decompression is life-saving and should be performed instantly upon recognition of this condition.
