Mr Biddle writes independent, clinically grounded expert reports in accordance with the Civil Procedure Rule 35 (CPR 35), specialising in all aspects of perioperative care across the full range of surgical specialities.

His structured and methodical approach reflects a comprehensive understanding of the entire patient journey from anaesthetic induction through to post-operative recovery and discharge. His reports deliver detailed analysis and expert commentary across key areas including: Airway management, resuscitation and emergency protocols, handling and administration of blood products, patient positioning and safety, Electro-biomedical engineering (EBME) equipment use, cell salvage techniques, perioperative equipment safety and compliance.

Each report is meticulously researched, clearly reasoned, and appropriately referenced, ensuring objectivity, transparency, and alignment with current clinical best practice and legal standards.

Mr Biddle has successfully completed the Bond Solon Expert Report Writing Course and produces reports that are robust, balanced, and court-ready. He accepts instructions from both Claimant and Defendant solicitors and is able to provide expert opinion on breach of duty, causation, and liability.

Mr Biddle has extensive experience in cases associated with:

Clinical negligence relating to:

• Anaesthetic related incidents:
  – Failed airway management
  – Unrecognised oesophageal intubation
  – Cerebral hypoxia
  – Intraoperative awareness from anaesthetic practitioner perspective
  – Can’t intubate, can’t ventilate (CICV)
• Local anaesthetic toxicity including high spinal and local anaesthetic systemic toxicity (LAST)
• Nerve damage arising from intraoperative positioning including:
  – Brachial plexus injury
  – Peroneal nerve palsy
  – Pressure neuropath
• Grade 1 – 4 pressure injuries linked to prolonged surgery and inadequate skin protection measures
• Complications arising from:
  – Laparoscopic
  – Roboitc
  – Cobotic surgery including CO2 gas embolism and positioning injury
• Burns and thermal injury
• Fire hazards associated with alcohol-based skin preparations and ignition sources in theatre
• Theatre environment issues:
  – Failure of laminar flow ventilation
  – Inadequate temperature or humidity control
  – Estates related deficiencies impacting infection control and patient safety
• Retained surgical swabs, instruments and sharps
• Surgical site infection associated with contamination, equipment failure, breaches in aseptic technique and inadequate cross-infection precautions for patients with resistant organisms such as Carbapenem-resistant Enterobacteriaceae (CRE), Vancomycin-resistant Enterococcus (VRE) and Methicillin-resistant Staphylococcus aureus MRS – resistant
• Failure to comply with the World Health Organisation (WHO) safety surgery checklist resulting in wrong site surgery or retained items
• Medication errors including opioid overdose, neuromuscular blockage reversal error, wrong medication administration via intravenous cannula and perioperative anaphylaxis
• Vascular access complications including:
  – Arterial injury
  – Haematoma
  – Air embolism
  – Catheter related sepsis
  – Infection arising from peripheral or central IV cannulation due to inadequate skin preparation or breach of aseptic technique and inappropriate cannula selection or removal
• Intraosseous (IO) access in emergency anaesthetic or perioperative scenarios including site selection, insertion technique, monitoring and associated complications
• Intraoperative warming and prevention of perioperative hypothermia including use of warming devices, temperature monitoring and active/passive rewarming strategies
• Surgical infiltration and irrigation complications including extravasation injury and local anaesthetic overdose
• DVT prophylaxis and perioperative antithrombotic measures including mechanical and pharmacological approaches
• Operating table attachments and positioning devices contributing to injury or equipment failure, including patient falls or limb entrapment under drapes or in steep Trendelenburg positioning
• Anaesthetic machine checking, maintenance and fault finding failures contributing to adverse outcomes
• Communication and human factors failures contributing to adverse events
• Surgical First Assistant (SFA), including retraction injury, nerve and tissue trauma, haemostasis, diathermy use, wound closure support, the standards of training and supervision defined by PCC, AfPP, and RCoS guidance
• Situations where the surgeon is assisted by individuals who may not have undertaken formal scrub or surgical assisting competencies, increasing the risk of procedural error or patient harm
• Failure to uphold patient dignity and support throughout the perioperative journey, including paediatric care, management of relatives or caregivers, mental health including capacity assessment and perioperative anxiety management considerations and the specific needs of older patients and individuals living with dementia
• Adult and paediatric Covid-19 cases
• Cardiac arrest protocols
• Transfusion practice
• Blood products and cell salvage, used in both practitioner position and the anaesthetist Improper use such as:
  – Lack of training
  – Contamination
  – Filtration using a leucodepletion filters
  – Cross matching errors
  – Transfusion errors leading to harm and death
  – Religious considerations
  – Parents not informed correctly of all the risk of blood products (laid out by NHS Transfusion Services)
• Obstetric surgery:
  – Scrub/assisting relating to nerve damage
  – Muscular damage
  – Massive haemorrhage
  – Equipment failures
  – Patient harm
• Anaesthetics
  – Drug errors
  – Patient positioning
  – Appropriate monitoring
  (Non theatre trained staff involved in the patient care midwives, paediatricians which increase the risks of the safe operating of the theatres workflow)
• Dual rolling refers to a situation where a scrub practitioner is expected to assist the surgeon while simultaneously managing and accounting for surgical instruments and consumables. While occasionally necessary due to unforeseen staffing shortages or emergencies, dual rolling must not become routine practice without rigorous oversight, risk assessment and proper documentation
  – Patient Safety Risks: The dual role can compromise both assistance to the surgeon and instrument tracking, increasing the risk of surgical errors or retained instruments
  – Staff Safety and Legal Liability: Practitioners may feel pressured or coerced into dual rolling without support, training, or adequate staffing, which places them at professional and legal risk
  – Surgeon Ambivalence: There is often a lack of engagement or acknowledgement from surgeons regarding the safety implications of dual rolling—until an adverse event occurs
  – Skill mix: Ensure the practitioner is trained and confident in both roles
  – Staff allocation: Evaluate whether there is an opportunity to redistribute roles among available team members to avoid dual rolling
  – Staffing numbers: Assess against recommended levels
  – Fatigue & working hours: Avoid dual roles during late lists or extended shifts
  – Recommendation of appropriate staffing levels laid out by the Association for Perioperative Practice (AfPP) and Royal College of Surgeons (RCoS), which is often ignored or stated that these are ‘recommendations’ only
  
• Record keeping should be an accurate, contemporaneous documentation, by theatre practitioners for core components of safe accountable perioperative care. Despite this, there is consistent and widespread issue within many operating departments where scrub practitioners and other theatre staff fail to complete or adequately detail their entries in patient records.

Personal injury relating to:

• Needlestick injuries and biological exposure incidents within the operating theatre
• Slips, trips and falls in perioperative areas causing fracture or soft tissue injury
• Occupational injuries linked to manual handling, patient transfer and prolonged static postures
• Theatre related environmental hazards including noise-induced hearing loss
• Burns and chemical injury sustained by theatre staff due to equipment or preparation misuse
