Intravenous (IV) extension sets with multiple ports: all brands. Risk of back-tracking when an IV line has multiple access ports. This can lead to under-infusion or bolus delivery of IV drugs.
09 Sep 2010
LIFEPAK 20/20e defibrillator/monitor. Manufactured by Medtronic/Physio-Control. Specific serial numbers are affected. Due to component failures, which affect AC (mains) and/or DC (battery) operating power, there is a risk that the defibrillator will not deliver therapy. The corrective action programme initiated by the manufacturer will take approximately two years to complete.

Action Update
Fetal monitor/cardiotocograph (CTG). Adverse outcomes are still being reported in the presence of CTG traces that appear normal. For example, the display of double maternal heart rate (MHR x 2) can be falsely reassuring.
28 June 10
Anaesthetic vaporizers used to administer volatile agents for the maintenance of anaesthesia - all manufacturers. The MHRA has received reports where the failure to correctly attach vaporizers to the anaesthetic machine backbar has led to anaesthetic gas leakage and patient awareness. This may be more pronounced where: vaporizers are attached to anaesthetic machines from an alternative manufacturer / vaporizers are attached to the backbar during anaesthesia.
16 June 10
Implantable vagus nerve stimulators (VNS): Pulse and Pulse Duo Generators (Models 100, 101, 102 and 102R); Demipulse and Demipulse Duo Generators (Models 103 and 104); Model 250 programming software. Manufactured by Cyberonics VNS Therapy. Premature battery depletion (models 103 and 104). Inaccurate battery life projection (models 103, 104 and 250). Loss of therapy (all models). Painful, erratic or atypical stimulation (all models).

All Aquarius haemofiltration machines. Manufactured by Edwards Lifesciences Ltd and supplied by Baxter Healthcare. Reports have been received of the wheels breaking due to wear or improper use. There is a risk of the machine toppling or falling over, which can cause injury and therapy interruption.
06 May 2010
All anaesthetic breathing systems, anaesthetic machines and anaesthetic ventilators. The MHRA continues to receive reports of inadequate patient ventilation and oxygenation where harm could have been avoided if an alternative means of ventilation had been used earlier. These incidents occurred because of misconnection, entrapment or occlusion of the anaesthetic breathing systems, or because the anaesthetic machine or ventilator had failed. In one particular incident an anaesthetic breathing system was wrongly connected to the auxiliary common gas outlet of an anaesthetic machine. The effects of this were wrongly interpreted as bronchospasm and the usual drug regimens were administered. The time taken to finally identify that this was a problem with the equipment meant that the patient was harmed. Whilst such equipment issues are uncommon, they should be considered as a matter of course when problems with patient ventilation occur.

It has recalled all of these devices.

Immediate Action
Hansen type coloured connectors on dialysis fluid lines used on Dialysis and Haemodiafiltration machines. All manufacturers. Potential for the red and blue Hansen type dialysis fluid line connectors to be incorrectly configured (interchanged) resulting in a significantly less efficient dialysis.
10 Feb 2010
Teligen implantable cardioverter defibrillators (ICDs) and Cognis cardiac resynchronisation therapy defibrillators (CRT-Ds) – specific models. Manufactured by Boston Scientific / For devices implanted subpectorally there are risks of: • loss of shock therapy • inappropriate shock therapy • loss of pacing therapy • loss of anti-tachycardia pacing
21 Jan 2010
Intraocular Lens (IOL) - Hydrophilic Acrylic. Opacification of IOLs may occur following intracameral use of alteplase (recombinant tissue plasminogen activator, r-tPA)
18 Jan 2010
Devices used for endometrial ablation. All makes and models / The MHRA continues to receive reports of uterine wall injury, wall perforation, or the creation of a false passage following use of endometrial ablation devices. In some cases resection of damaged tissue has been required. The majority of complications occur due to either poor patient selection or endometrial ablation procedures being performed in difficult situations. Patients with either a retroverted uterus or a fixed uterus (e.g. due to significant endometriosis or adhesions), or those that have had previous uterine surgery are at a higher risk
05 Jan 2010
All types of bed mattresses / If mattress covers are damaged, body or other fluids can pass through and contaminate the inner core. There is the potential for cross-infection if contaminated mattresses remain in use
