Risks of transport of critically ill patients Technical complications: e.g. displacement of the tracheal tube, intravascular lines, drains etc. Pathophysiological deterioration: e.g. increased intracranial pressure as may occur from the lowering of a head-injured patient from semirecumbent to recumbent position for a CT scan), arterial hypotension, decrease in oxygen saturation. Inadequate monitoring of cardiovascular and pulmonary function due to less sophisticated monitors or equipment/interference due to motion, etc. Inadequate therapy due to lack of appropriate equipment – many transportation ventilators cannot deliver the modes or levels of ventilation as a high-end ICU ventilator. (Note newer ICU ventilators may be used for transport and are even becoming MRI compatible). Additional movements during transport (acceleration forces during aeromedical or ambulance transport, tilting/lifting of patients from bed to trolley), may cause dislocation of fractures, fibrin clots, sutures, vascular emboli, etc.). Lack of immediate access to additional investigations or therapy if needed e.g. no chest X-ray in an ambulance to diagnose/exclude a pneumothorax or extra unit of packed cells/clotting factors in case of acute haemorrhage.

(Note newer ICU ventilatorsmay be used for transport and are even becoming MRI compatible). Additional movements during transport (acceleration forces duringaeromedical or ambulance transport, tilting/lifting of patients frombed to trolley), may cause dislocation of fractures, fibrin clots,sutures, vascular emboli, etc.). Lack of immediate access to additional investigations or therapy ifneeded e.g. no chest X-ray in an ambulance to diagnose/exclude apneumothorax or extra unit of packed cells/clotting factors in case ofacute haemorrhage. Limited number of people involved in the transport, lack of moresenior people immediately to handWhich patients and situations face an increased risk of adverseevents during transport, and why?A. Paediatric patients: even small movements of the patient or associatedequipment (e.g. endotracheal tube) may lead to disconnection or dislocation ofthe tubes and lines. Transfer at night: this may mean fewer staff or staff with less experienceresulting in sub-optimal planning, preparation of conduct of transfer. Poorlighting may impair tasks and make correct dosage of medications or therecognition of complications more difficult. Patients with increased intracranial pressure: often it is not possible to elevatethe upper body for transport and positioning of the patient e.g. in the CT orMRI suite. Patients with increased positive airway pressure (> 4050 cmH20) duringventilation: many transport ventilators will not generate enough drivingpressure or PEEP to sufficiently oxygenate very obese patients or those withsevere ARDS. Abrupt change of clinical team: information may be lost if the transfer team hasno connection with the team previously providing care and has not hadsufficient time to get a proper clinical picture of the patient. Every handover ofinformation poses the risk of information being lost

What to monitor Three-lead (or more) ECG with heart rhythm and assessment of theST segment Invasive pressures (or if too time-consuming or not available, noninvasiveblood pressure may be acceptable) Haemoglobin oxygen saturation End-tidal capnography Temperature.During transfer of mechanically ventilated patients with serious headinjury, monitoring end-tidal capnography is crucial to prevent hyper- orhypocapnia with possible cerebral vasodilation or constriction and consequentchanges in intracranial pressure or ischaemia.Before any transport, the staff check: If enough spare syringes are available to cover the patients needs duringtransport For special and adequate tubing, depending on the type of pump For battery power and number of wall sockets available in the ambulanceor at the receiving site Which medications are indispensable and which may be interruptedtemporarily.syringe pumps, e.g. mcg/kg/min, mcg/min, mg/hour, ml/hour,or even number of drops/minute in infusion pumpspressure bags oradditional infusion pumps may be needed for every infusione.g. suction of tracheal ororal secretionsHow useful to patient care during the transport is the device? What are the risks for the patient if the device is displaced unintentionally (e.g.blood loss)? What is the battery capacity and what are the risks to the patient if the deviceshuts down? Is it safer to uncouple the device during transport because the risks outweighthe benefits? Do weight, size, possibility of firm attachment to ambulance or legal restrictionspreclude the use of a device, especially in aeromedical transport?Set appropriate alarm limits and ensure the alarm volume is loud enough to beheard.e.g. which model of a hip prosthesis. Based onclinical experience most implanted devices (such as stents, prostheses) withoutelectronic control are suitable for MRI. Electronically controlled devices, such asTask 3. Conduct of the transfer[24]pacemakers or infusion pumps, may not function properly during and after MRI and aneed for their presence precludes MRI scanning. Standard medical devices such asventilators or infusion pumps are not compatible with MRI and specialarrangements/equipment must be used.What may happenAdverse events (e.g. desaturation, persistent hypotension) or specific transportrelatedevents (e.g. unintended extubation, loss of intravascular access) shouldbe handled according to standard critical care practice.Even a simple medical interventionsuch as placement of an intravenous lineBefore transporting a patient after resuscitation for haemorrhagicshock, check that red blood cells and clotting products (platelets, fresh frozenplasma or concentrated factors) are availableDifficulty keeping the airway open, e.g. obesity and increased sleepinessfollowing morphine. Airway protection deserves special consideration in case ofincreased nausea or vomiting. Difficulty ventilating, e.g. heavy snoring, worsened sleep apnoea with obesityand morphine. Difficulty oxygenating, e.g. pulmonary oedema in left ventricular failure.Duration of the transfer? Role assignment of the team. Space for all the equipment.Connections to tubes and lines. Is the CT suite ready for the procedure and are thecorridors clear?Changing ventilators (with possible loss of PEEP), syringes on pumps or othertherapeutic equipment pose hazards. Frequent pitfalls include three-way stopcocksleft in the wrong position and errors with syringe pumps containing vasopressorsIndications for transportation.All equipment should be robust, durable and lightweight. Electrical equipmentmust be designed to function on battery when not plugged into the mains.Additional batteries should be carried in case of power failure. Battery life shouldbe maximised by exercising batteries in compliance with the manufacturers recommendations.8.6 Portable monitors should have a clear illuminated display and be capable of displayingECG, arterial oxygen saturation (SaO2), non-invasive blood pressure, threeinvasive pressures, capnography (EtCO2) and temperature. Alarms should be visibleas well as audible in view of extraneous noise levels.8.7 Portable mechanical ventilators should have as a minimum disconnection and highpressure alarms, the ability to supply positive end expiratory pressure (PEEP) andvariable inspired oxygen concentration (FiO2), inspiratory/expiratory (I/E) ratio,respiratory rate and tidal volume. In addition the ability to provide pressure controlledventilation, pressure support and continuous positive airway pressure(CPAP) is desirable.8.8 Gravity feed drips are unreliable in moving vehicles. Sufficient syringe or infusionpumps are required to enable essential fluids and drugs to be delivered. Pumpsshould preferably be mounted below the level of the patient and infusion sets fittedwith anti-siphon devices.8.9 Portable warm air devices for maintaining patient temperature can be useful and canalso be mounted on the patient trolley.8.10 Additional equipment for maintaining and securing the airway, intravenous access,etc should also be available (Appendix 1).8.11 High visibility clothing, a mobile telephone, contact telephone numbers, money/credit cards should be available for use in emergencies.Intubated patients should normally be paralysed, sedated and mechanically ventilated.Inspired oxygen may be guided by arterial oxygen saturation (SaO2) and ventilationby end tidal carbon dioxide (EtCO2). Following stabilisation on the transportventilator, at least one arterial blood gas analysis should be performed prior to departureto ensure adequate gas exchange. Inspired gases should be humidified using adisposable heat and moisture exchanging filter (HME).13.6 If a pneumothorax is present or likely, chest drains should be inserted prior to departure.Underwater seals should normally be replaced by leaflet valve (Heimlich type)drainage systems. Chest drains should not be clamped.13.7 Secure venous access is mandatory and at least two wide bore intravenous cannulae(central or peripheral) are required. A suitably secured indwelling arterial cannula isideal for blood pressure monitoring.13.8 Hypovolaemic patients tolerate moving poorly and circulating volume should be nearnormal prior to transportF2 . This may require volume loading with crystalloid, colloidor blood, guided by central venous or pulmonary artery occlusion pressure monitoringand cardiac output measurement. If inotropes or other vasoactive agents arerequired to optimise haemodynamic status, patients should be stabilised on thesebefore leaving the referring unit.13.9 Patients who are persistently hypotensive despite resuscitation efforts should not bemoved until stable. Continuing sources of blood loss or sepsis should be identifiedand controlled. Long bone fractures should be splinted to provide pain relief, cardiovascularstability and neurovascular protection.13.10 A naso- or orogastric tube and urinary catheter should be passed and free drainageallowed into collection bags.13.11 Conscious patients should be kept informed of the transfer and all other relevantinformation. Relatives should similarly be kept informed of travel arrangements butshould not normally travel with the patient.13.12 Before departure, named medical and nursing personnel at the receiving unit shouldbe contacted to confirm the availability of the bed, update them on the patientscondition and provide an estimated time of arrival.13.13 The means of return to base hospital for the medical and nursing staff accompanyingthe patient should be established.MONITORING DURING TRANSPORT14.1 The standard of care and monitoring during transport should be at least as good asthat at the referring hospital or base unit20. The minimum standards required for allpatients are:_ Continuous presence of appropriately trained staff_ ECG_ Non-invasive blood pressure_ Arterial oxygen saturation (SaO2)_ End tidal carbon dioxide (EtCO2) in ventilated patients_ Temperature (preferably core and peripheral).In mechanically ventilated patients the oxygen supply, inspired oxygen concentration(FIO2) ventilator settings and airway pressure should be monitored.14.7 A written record of patient status, monitored values, treatment given and any otherclinically relevant information should be completed during the transfer.SUPPLEMENTARY EQUIPMENT FOR USE DURINGTRANSPORTAirway Guedel airways (assorted sizes) Laryngeal masks (assorted sizes) Tracheal tubes (assorted sizes) Laryngoscopes (spare bulbs andbattery) Intubating stylet Lubricating gel Magills forceps Tape for securing tracheal tube Sterile scissors StethoscopeVentilation Self inflating bag and mask withoxygen reservoir and tubing High flow breathing circuit Spare valves for portable ventilator Chest drains (assorted sizes) Heimlich flutter valvesSuction Yankauer sucker Suction catheters (assorted sizes) Nasogastric tubes (assorted sizes) anddrainage bagCirculation Syringes (assorted sizes) Needles (assorted sizes) Alcohol wipes IV cannulae (assorted sizes) Arterial cannulae (assorted sizes) Central venous cannulae Intravenous fluids Infusion sets/extensions 3 way taps Dressings Tape Minor instrument/cut down set
