Landing Zone Preparation & Communications Why is this so important?
Undesignated / Spontaneous LZs • High risk –espc at night • Obstacles on approach Wires Cell Towers • Ground hazards – signs, poles debris • LZ security – people vehicles • How well was it scouted out –we are 100% dependent on your eyes
Alternate LZs.You don’t have to land the helicopter exactly at the accident scene That’s why God put wheels on the ambulance
Communication • MF dispatch 608-263-3258 • Your county 911 dispatch • Cell contact on scene
Initial Info • Location – street and cross street • Relationship to city, well known landmark • Contact agency • Cell contact on scene • Contact frequency – Typically Marc 2 • Incident type and basic patient info • Do you need more than 1 helicopter?
Radio contact • MARC 2 • 5-10 minutes out • Use vehicle radios – handheld have limited range • Our #1 interest – LZ information • VERY brief patient update
Common LZ Problems • Personnel “marking” the LZ • Personnel approaching aircraft before blades stop turning • LZ security once helicopter lands • LZ has to be secured 5 minutes prior to landing until 2 minutes after takeoff • No vehicle, regardless of height within 50 ft of aircraft. Especially ambulances
Large Patients Im not afraid of heights Im afraid of widths
A Slippery Slope.. • Car 1 looses control on ice at highway speeds • Collides with car 2. Both go over 30 degree embankment • Car 1 slides sideways, impacts tree into drivers door • Car 2 T-bones Car 1 into passenger side
2 occupants of car 2 self extricate –minor injuries • EMS arrives – Extensive damage toCar 1. Driver is obviously pinned. Talking but confused • Walmart parking lot 200 yrds from scene • Med Flight called – Landed within 15 minutes
Significant intrusion on both passenger and driver doors • Pt alert, confused, slightly agitated. Pinned by legs • Complaining of chest/abd pain • Collar placed. IV established, O2 • Initial VS 150/80 100 18
Wisconsin EMS Rule 11a If it is Saturday night and you respond to an accident scene after 10pm and do not find a drunk- Keep looking because you are missing a patient
CAR 2 CAR 1
Initial Approach • Car 2 winched up towards highway exposing passenger side of Car 1 • Plan is to remove passenger door and top
Additional support personnel beamed down from the Enterprise
Passenger side is no go • Now at 50 minutes post incident • Outside temp 35 F • Patient becoming more agitated-yelling • BP dropping 100/70 • Lets hold things for a minute..
Medical Interventions • Given Ketamine 50 mg IVP • IO placed in L humeral head • Concern re internal bleeding –TXA • Started PRBCs
Pt BP improves slightly • Dissociated state –protecting airway • T= 50 mins Tree cut away • Top removed • Pt starts to vomit and vomit and vomit
EMS rules regarding vomit • The volume of vomit always exceeds the size of the container be a factor of 2 • Standard suction is useless for Saturday night puke ( consists of McNuggets & partially chewed burritos pressurized by a pitcher of Milwaukee's Best) –you need a shop vac • Always point the pt at the person you like least
Tailoring the Extrication (speed/spinal precautions) to the patients condition & environmental issues
Situation a little more urgent • Pt quickly put in a KED • Lifted out – put on long board • Transferred to ambulance
In the Ambulance • Initial GCS 13 –now 7 • Pt intubated using Glidescope • Given 2 units of PRBCs • 10 minute flight • To the trauma bay….
In The Emergency Dept • BP 90-100 systolic • Labs –hgb 8.5 Etoh 0.19 • FAST exam with ultrasound positive • CT scan of head/neck – negative • CT Scan of abd/pelvis – extensive splenic laceration
What is a FAST exam?Focused Assessment by Sonography for Trauma
Taken to the OR • Uneventful splenectomy • Transfused total of 4 units PRBCs • Discharged to home POD 5
16 y/o healthy female • Alone in the lap pool at waterpark • Found unresponsive in 4 ft of water • Immediately picked up on security video • Submerged 3-4 mins MAX • Park EMTs pull her from water, no pulse • 911 called • Start CPR, AED applied, shock advised • Immobilized, C-collar
We have a pulse • Local paramedic service arrives • VS 110/60 HR 120 irreg • Bagged on 100% O2 sats 85% • No evidence of trauma • Frothy sputum, bilat rales • GCS 6-7 Pupils 4-5mm reactive • IVs x 2
Prior to MF • Pt intubated, high airway pressures • Freq suctioning, • 12 lead –freq multifocal PVCs, no STEMI • MF lands at hospital helipad as ambulance arrives
Handoff • Vital signs and Neuro status unchanged • Pt sedated, paralyzed put on ventilator • What is the history again??
Uneventful flight Home • Handoff to ED • Evaluated in ED – head CT NL • CXR – pulmonary edema • Most labs and studies c/w drowning • Admitted to PICU • Its just another tragic drowning..
Whats the history again? • 16 y/o healthy 5’ 7” • No etoh, drugs, trauma • Lap pool is 4’ deep • Call to the water park – Can you pull the security videos? • What about the initial AED?
