A few days ago, I wrote about our first day of field trials for an open source 3D printed tourniquet in Gaza. The Glia team worked overtime to address and fix the problems we identified. Thanks to help from the 3D printing, engineering and open source communities, we got lots of feedback and felt that we were ready for today.


Good news first: The tourniquets worked well

The tourniquets worked well. We recovered the 100 units given to Hayat Center for use in the field, giving us an inventory of 200 deployed units. One hundred units were distributed in the field today, and one hundred held in reserve for May 15. Seventy-eight (78) tourniquets were deployed to patients who met criteria. There were no failures of the device in any cases.


Failure #1 rules supreme: Unsafe conditions for medical personnel

The unspoken part of this is optimizing safety. To ensure the safety of first responders, we all dressed in clearly identifiable medical garb. Most paramedics wore fluorescent high visibility jackets. I wore a hospital green top and bottom so I could both be identified as medical staff and a physician.

Despite our efforts to clearly identify ourselves as first responders, several of our medical team were wounded by Israeli live fire. One paramedic, Musa Abuhassanin, was killed while attempting a victim rescue under fire. One hour before he was shot in the thorax and killed, Musa was one of my rescuers when I was shot by live ammunition. I sustained a moderate injury to my left leg and a minor one to the right leg. Musa was also the paramedic who discovered and reported the failed buckle in our previous report. He had a great laugh and was a good paramedic.

Anatomy of my gunshot wound

I was shot toward the end of the morning, and we had already run out of our first supply of tourniquets. I had just resupplied with 8 units, one of them unpacked in my pocket. We were standing well away from the main protest area. The snipers in the three sniper outposts all had clear views of us.

There was no fire or smoke near us. We were standing still, and I was facing in a southerly direction talking to a colleague. The snipers were situated east of us. I was wearing visible full hospital greens. There was no active shooting from the Israelis immediately before or after. There were no protesters in our immediate vicinity.

I heard a loud bang and found myself on the ground. The bullet had entered my left proximal calf on the lateral side, exited on the medial side (moderate) and pierced my right knee superficial to the patella (minor). I yelled fuck.

The paramedics initiated treatment within 5 seconds, and asked me if I needed a tourniquet. The wound had about 100cc of blood lost on the scene, but didn’t look to be bleeding dangerously. I believe that I was shot with a regular bullet and not the exploding bullets that are causing severe injuries reported today and on other days. Knowing the shortage, I stopped the application of the tourniquet, and was instead given a pressure dressing. There was no live fire before or after my incident.

I was transported to hospital, stabilized and discharged after X-Rays showed no bony injury.

Conclusions

The tourniquets appear to be feature-complete and usable as is. We will continue to monitor and develop the tourniquets, especially thanks to the community support offered in improving the design.

However, it is clear that conditions remain suboptimal for tourniquet deployment by paramedics at this time. One possible solution is the wide deployment and routine training of the general Palestinian population in the use of tourniquets, such as in Basic Life Support (BLS) courses.


Dedicated to the brave women and men of Gaza’s paramedic and front-line response teams.
