Trick of Trade: Removal of Entrapped Metal Zipper

zipper entrapment injury

A young boy is brought to the pediatric emergency screaming at the top of his lungs by his parents. His penile skin is trapped in the zipper of his jeans. On a busy shift, you want a simple way to handle zipper injuries that minimizes pain, doesn’t require resource-intensive procedural sedation, and is quick.

Background

The 4 most common types of zippers are nylon coil zip, plastic mold zip, metal zip, and invisible zip. Most of the techniques describing solutions on zipper entrapment in the medical literature are derived from case reports and case series. All revolve around understanding zipper anatomy and obtaining adequate exposure to assess how the skin is entrapped. The penile skin often is entrapped either in the sliding mechanism (also known as the endplate) or between the teeth of the zipper.

Penile Entrapment Injury Management Techniques in Literature

Reported techniques for releasing zippers include [1, 2]:

  • Cut the sliding mechanism (aka the endplate) using metal cutters.
  • Use a flat screwdriver placed underneath the sliding mechanism and rotate it.
  • Use mineral oil for lubrication.
  • Use lateral compression technique to relieve the tension on the trapped skin.
  • Cut the zipper and pull the teeth apart.

All these techniques are associated with variable rates of success. Some of these techniques such as using metal cutters might lead to iatrogenic injuries.

The problem is that the child’s penile skin is entrapped within a metal zipper, where many recommended methods for zipper entrapment removal won’t work.

Trick of the Trade: Removing Metal Zippers

Materials Needed

  • Lidocaine gel
  • Blade or scissors

Technique

  1. The zipper should be separated from the pants as much as possible to minimize painful stretching or pulling of the penile skin.
  2. Apply lidocaine gel on the area of entrapment for 2-3 minutes.
  3. Identify the exposed teeth closest to slider and cut off the zipper at that level (blue dots) while avoiding penile skin (Figure 2).
  4. Gently advance the zipper body forward, pulling either the tab or the body itself, to disengage it from the teeth. You may need to add more lidocaine gel or other lubrication to facilitate this sliding motion.
  5. The remaining parts of the zipper can easily be disengaged from the skin (Figure 3).

Trick of Trade: Inflating the Esophageal Balloon of a Blakemore/Minnesota Tube without a Manometer 

esophageal balloon manometer trick minnesota blackmore tube

A heavy alcohol drinker, who is well known to your Emergency Department, presents with altered mental status, except that he looks different this time. He looks really bad, stating that he has been vomiting blood. He is hypotensive. He then vomits a copious amount of blood right in front of you. You intubate the patient and initiate the massive transfusion protocol, but everything you pour into him seemingly comes right back out. The gastroenterologist on-call states that he is too unstable for endoscopy. It is time for a balloon tamponade device. You’ve trained for this and set up everything. You call the respiratory therapists (RT) for this mystical “manometer” that you have seen in instructional videos, except that they look puzzled by your request. It is time to MacGyver a method that allows you to know the esophageal balloon pressure that you are generating to avoid an esophageal rupture.

What are esophageal balloon tamponade devices?

There are 2 commonly used devices for tamponading the esophagus during a variceal bleed, the Sengstaken-Blakemore (SB) tube and the Minnesota tube. There is also the Linton-Nachlas tube, but that only has a gastric balloon. The SB tube was created in 1950 in order to help tamponade variceal bleeds [1]. It is a 3-lumen device that has ports to inflate the gastric balloon, aspirate gastric contents, and inflate an esophageal balloon. The Minnesota tube was developed later as a variation to the SB tube and contains an additional port and lumen for aspirating esophageal contents [2]. Another minor difference is that the gastric balloon in the Minnesota tube holds 450-500 ccs of air, while the SB gastric balloon holds 250 ccs of air [2].

Indication: The uncontrolled hemorrhage from esophageal or gastric variceal bleeding after medical or endoscopic treatment fails, is not available, or is not technically possible [3, 4].

Contraindications [4]:

  • Unprotected airway
  • Esophageal rupture (Boerhaave’s syndrome)
  • Esophageal stricture
  • Uncertainty of bleeding site
  • Well-controlled variceal bleeding

Esophageal balloon tamponade devices achieve hemostasis in 60-90% of cases; however, they are only a temporary measure of hemorrhage control because over 50% of variceal bleeds rebleed after deflation [5].

How do you insert these esophageal tamponade devices?

The following instructions are for inserting a Sengstaken-Blakemore (SB) tube [3, 6]:

  1. Pre-measure 50 cm above the gastric balloon and esophageal balloon and mark them on the SB tube.
  2. Fully lubricate the tube.
  3. Insert the tube similar to an orogastric tube until you have reached the 50 cm mark for the gastric balloon
    • Additional trick: You can insert it with a nasogastric tube to have more rigidity and make inserting the tube easier.
  4. Use a slip syringe at the gastric aspiration site and auscultate to confirm that you are in the stomach. Then fill the gastric balloon with 50 cc of air.
  5. Verify the placement of the gastric balloon with a chest x-ray.
    • Additional trick: If the x-ray is delayed, you can pre-check with ultrasound [7]. However final confirmation prior to full inflation should be with a chest X-ray.
  6. Fully inflate the gastric balloon with 200 more ccs of air for a total of 250 ccs.
    • The Minnesota tubes should have the gastric balloon inflated to 450-500 ccs.
  7. Apply traction to the tube by tying a roller bandage to the end of it and then the other end to a 1 L bag of IV fluids. Then hang the roller bandage over an IV pole.
  8. Place the nasogastric tube down to the pre-measured level above the gastric balloon and suction the esophageal space. If there is continued bleeding coming from the nasogastric tube then you will need to inflate the esophageal balloon.
    • Note that Minnesota tubes already have their own esophageal suction port and will NOT need this NG tube placement to suction the esophagus.
  9. Use a “manometer” to inflate the esophageal balloon to 30 mmHg. If bleeding persists, you can go to a maximum of 45 mmHg.

What is this “manometer” typically used for the esophageal balloon?

The manometer referenced in numerous videos [6, 8] is actually a cuff manometer, or pressure gauge, to measure endotracheal cuff pressures. Hence, the RT’s are supposed to have them. In our emergency department, the RTs do not spend a lot of time going around measuring cuff pressures and usually save that until the patient reaches the ICU. It is convenient to use for the inflation of the esophageal balloon because it can inflate and measure pressure at the same time.

Pearl 1: Check the units of pressure being used. Manometers often use cmH2O, while esophageal balloons use mmHg.

  • The conversion rate is: 1 cmH2O = 0.74 mmHg
  • The esophageal balloon goal of 30-45 mmHg is approximately 40-60 cm H2O.

Pearl 2: While the gastric balloon sets a target VOLUME, the esophageal balloon sets a target PRESSURE.

Trick of the Trade: Use a sphygmomanometer as the manometer

Once the inflated gastric balloon is confirmed to be in place, it is time to inflate the esophageal balloon. A manual blood pressure instrument can be repurposed to inflate and measure the esophageal balloon pressure.

  1. Take your manual blood pressure cuff and detach the connections so you have only a plastic tube that runs to the pressure gauge.
  2. Connect this plastic tube end to the male Luer lock of a 3-way stopcock.
  3. Connect the esophageal balloon to a female luer lock on the 3-way stopcock.
  4. Place a 50 cc syringe on the final female Luer lock of the 3-way stopcock.
  5. Turn the 3-way stopcock off towards the pressure gauge and inflate the esophageal balloon with 10 ccs of air.
  6. Then turn the 3-way stopcock off towards the syringe and you should have a reading on the pressure gauge.
  7. Repeat this using small increments (we chose 10 ccs) until you have a pressure reading of 30 mmHg on the pressure gauge. If bleeding continues, you can increase to 45 mmHg.

Trick of the Trade: Gel-free ultrasound-guided peripheral IV technique

Ever finally step away from a busy resuscitation and someone stops you for peripheral IV access? You set up everything, have the patient positioned, and then notice there is no sterile ultrasound gel. No gel? No problem. The trick is to eliminate anything of poor acoustic impedance between the ultrasound probe and the patient’s skin.

Trick of the Trade

1. Apply a transparent adhesive dressing with a thin alcohol layer on the probe

Instead of using gel, we squeeze alcohol pads to create a thin alcohol layer and place a transparent adhesive cover, such as Tegaderm ©. The thin alcohol layer serves to eliminate any air bubbles under the adhesive cover as well as minimizes residual adhesive material sticking to the probe when removing the cover. The adhesive cover itself serves as a sterile barrier and a slick surface to improve probe maneuverability. Note that some ultrasound manufacturers do not recommend the use of isopropyl alcohol on their transducers. Therefore check your specific ultrasound’s recommendations before trying [1, 2].

2. Use sterile saline instead of gel on the patient’s skin

Squirt normal saline flush on the patient’s skin to create a coupling medium between the probe and the patient.

Why it works:

Ultrasound procedures use a range of frequencies (1.5-20 MHz) to visualize internal structures and require a medium to replace air, which has a poor acoustic impedance for the ultrasound waves [3]. Acoustic impedance is defined as the resistance of the propagation of ultrasound waves through tissues and is the product of the density and speed of sound in the tissue [4]. Ultrasound gel has an acoustic impedance that is similar to soft tissue and is therefore considered the ideal medium [3]. Because most soft tissue is comprised of water, the acoustic impedance of water, and therefore 0.9% saline, is actually pretty similar [5], as demonstrated by water bath techniques for ultrasounding distal extremity injuries [6].

We find great visual clarity for performing ultrasound-guided peripheral IVs using this trick, as shown in Figure 1.

Trick of the Trade: Chest tube rewarming with Foley tubing connector

You have a pulseless hypothermic patient requiring aggressive internal rewarming. ECMO is not available, and you’ve made the decision to initiate thoracic lavage. After placing your chest tubes, you step back triumphantly, but in short order, the nurse hands you large diameter IV tubing with warmed fluids so that you can connect it to the chest tube. You are left with the IV tubing in one hand and a chest tube in the other with no time to waste, but no elegant or straightforward solution to interface the two.

Trick of the Trade

Using Foley bag tubing

The tube from a standard Foley bag, available in all emergency departments, contains a Luer lock near the tapered nozzle. This unique connector setup allows you to instill warm fluids into the thoracic space with minimal spillage.

rewarming hypothermia IV tubing chest tube foley tubing

Technique for Rewarming

  1. Attach the warmed IV fluids to the Luer lock port on the Foley bag tubing.
  2. Insert the tapered nozzle on the Foley bag tubing (typically interfaces with the urine drainage port of the Foley catheter) into the chest tube.
  3. Clamp the remainder of the Foley bag tubing just proximal to the Luer lock to minimize backflow of IV fluids into the bag.
  4. Optional: Cut the tubing proximal to the clamp to declutter the space around the interface.
  5. Instill warm fluid through one chest tube and drain it from the adjacent chest tube.
  6. Continue rewarming resuscitation protocols.

Trick of the Trade: Antibiotic ointment for removal of artificial nail glue from eyelids

A bottle of nail glue and timolol eye drops (reproduced with permission from BMJ Publishing Group Ltd [1])

You are working a busy shift in your department’s fast track area and sign up for a patient with a complaint of “eye pain.” The patient is a fan of glue-on nails and mistook her nail glue bottle for her eyedrops. Now she is unable to open her eyelid for the exam and you struggle to open it yourself. You want to avoid cutting the adhered eyelashes and wonder if there’s a better solution.

Background rise of artificial, press-on nails

Artificial acrylic or “press-on” nails were first invented in the 1950s; however, they did not gain in popularity until the 1980s as nail art became a trend [2]. Shortly thereafter, they fell out of style until a resurgence occurred with the COVID pandemic forcing the closure of nail salons. Compared to pre-pandemic values, Google searches for “press on nails” increased 300% [3]. Application of most nails requires nail glue, which often contains a mixture of alcohol, cyanoacrylate (superglue), or photo-bonded methacrylate [4].

Nail glue complications

Use of nail glue at home can result in adverse exposures with the most common location being the eye [5]. Because nail glue is often packaged in small containers identical to eye drop bottles, patients can mistake the nail glue for ophthalmic drops — especially those with visual impairment [6]. This exposure was first described in the medical literature in 1982 and has been described many times since despite repeated calls for manufacturers to modify the bottles to be safer [1].

In the presence of water, cyanoacrylate rapidly polymerizes, leading to the bonding effect [5]. If the glue gets into a person’s eye, reflexive blinking pushes the glue to the eyelid margins resulting in the eyelashes or eyelid margins sticking together [5], also known as inadvertent tarsorrhaphy. Methods to open the eyelids include removal of glue with forceps, removal or cutting of the eyelashes, or soaking the eye for hours to days with a moist gauze [1, 6, 7].

Although the most successful solvent to dissolve dried glue is acetone, this can cause corneal and conjunctival injuries [8]. The effectiveness of other solvents has been debated in the literature with mixed reports of efficacy [9].

Trick of the Trade: Apply petroleum-based topical antibiotic ointment

Our personal experience managing several of these cases suggests that a petroleum-based topical antibiotic ointment, such as Bacitracin, can help loosen the glue bond. It is an inexpensive option with minimal harm to fix inadvertent eyelid adhesion from nail glue (or other superglue). It is worth trying before attempting more aggressive techniques.

Before and after application of topical antibiotic ointment to remove inadvertent nail glue causing eyelid adhesion

Materials Needed

  • Bacitracin ointment (1-2 tubes)
  • Cotton-tipped applicatiors (Q-tips)

Technique

  1. Apply the topical ointment liberally to the affected eye.
  2. Let rest undisturbed for 15-20 minutes.
  3. Gently pull the eyelids and eyelashes apart.
    • Be careful not to massage the area too vigorously onto the eye itself, as any residual local glue can result in corneal trauma.
    • You can use cotton-tipped applicators to help gently tease the lid margins apart.
  4. Copiously irrigate the eye.
  5. Perform an eye exam to assess for ocular injury.
  6. Consider obtaining an ophthalmology consult.

Trick of the Trade: Managing Epistaxis with Merocel Nasal Packing and an Angiocatheter


There are many ways to manage epistaxis. Once nasal clamping and cauterization fail, the next step is to consider using tranexamic acid (TXA) and performing nasal packing. Inflatable packing devices such as a Rhinorocket are painful to insert and do not conform well to the shape of the naris. The expandable Merocel nasal packing, a compressed, dehydrated sponge, provides a softer, alternative option, although the insertion process can be painful given its initial rigid, edged structure. We propose 2 strategic tricks to optimize your nasal packing technique using the Merocel sponge.

Trick of the Trade: Strategic expansion of the Merocel sponge

The common approach for Merocel packing involves inserting the unexpanded sponge into the nose, tilting the patient’s head back, and dripping in TXA solution to expand the sponge to tamponade the bleeding.

Trick #1: Wet the tip of the Merocel’s sharp edge to allow for a softer cushion to slide the packing more comfortably and deeper into the naris.

Trick #2: Use an angiocatheter to deliver the TXA solution directly onto the mid-portion of the packing. Commonly, the TXA solution is dripped onto the outer end, which may cause an uneven and inadequate expansion at the site where the bleeding may be occurring. Because blood also can react with the packing, it is likely the blood will expand the packing before TXA reaches the center by osmosis. Another benefit of Merocel expansion starting at the center is that it will help anchor the sponge in place. In contrast, TXA administration at the outer tip first may pull the sponge out of the naris a few millimeters.

Equipment

  • 20g or 22g angiocatheter (closed IV catheter system)
  • Tranexamic acid solution
  • A syringe
  • Merocel nasal dressing

Technique

merocel sponge nasal packing trick setup

1. Insert the angiocatheter needle into the Merocel packing about ⅓ the distance from the external end of the packing. Remove the needle, leaving the plastic angiocatheter in place.

2. Soak the insertion tip of the nasal packing with a drop of TXA to soften it. Or apply a light coat of an antibiotic ointment or petroleum jelly to the insertion tip for lubrication. This will make it easier to advance the packing and also less painful for patients. Advance the Merocel into the affected naris just as you would a nasogastric tube. Some additional tips are in the ALiEM article about nasogastric and nasopharyngeal tube insertion.

3. Once the nasal packing is fully inserted, expand the sponge by administering TXA via the attached angiocatheter. The mid-portion of the sponge should expand first, thus preventing outward slippage of packing. Also TXA more quickly reaches the area of bleeding rather than from a more gradual osmotic effect when dripped in from the external tip.

Trick of the Trade: Winging It with External Jugular Cannulation

external jugular

Sankoff J, et al. WJEM (2008)

Imagine yourself caring for a patient that needs urgent vascular access, but several attempts at peripheral intravenous (IV) cannulation have been unsuccessful. You aren’t quite at the point where emergent intraosseous or central venous access is indicated. Maybe those options aren’t even available where you’re working. From across the room, though, you can see a very prominent external jugular (EJ) vein. Sadly, you remember the last EJ line you placed falling out almost immediately.

Patients with challenging peripheral intravenous access in the extremities may require and benefit from cannulation of the EJ. Often done in the setting of resuscitation, securing these angiocatheters on the neck can be difficult. Tape and dressings may not stick due to sweat and anatomical limitations. Rotation, flexion, and extension of the neck can displace the catheter.

Trick of the Trade

If available, modify a winged angiocatheter to allow suturing to the skin of the neck.

angiocatheter

  • Create two small holes, one on each wing of the angiocatheter, using a sharp instrument such as scissors, scalpel, or needle.
  • Place EJ line and secure to the skin using sutures, similar to stabilization of central or arterial line.

Winged angiocatheters may not be available in all clinical institutions. International readers of ALiEM may be more familiar with their use.

However, this trick introduces the idea of finding creative modifications of available catheters to allow for suturing and securing of alternative IV lines. Modifications similar to this Trick of the Trade can be considered when placing “deep” peripheral IVs or pseudo-midline IVs such as when using extended-length angiocatheters or repurposed arterial catheters where suture can be wrapped around the hub. This approach may also be useful in peripheral cannulation of the internal jugular vein. 

Tip: Be careful not to pierce the catheter or compress it down when suturing.
