Patient-maintained versus anaesthetist-controlled propofol sedation during elective primary lower-limb arthroplasty performed under spinal anaesthesia: a randomised controlled trial (2021)
Journal Article
Hewson, D. W., Worcester, F., Sprinks, J., Smith, M. D., Buchanan, H., Breedon, P., Hardman, J. G., & Bedforth, N. M. (2022). Patient-maintained versus anaesthetist-controlled propofol sedation during elective primary lower-limb arthroplasty performed under spinal anaesthesia: a randomised controlled trial. British Journal of Anaesthesia, 128(1), 186-197. https://doi.org/10.1016/j.bja.2021.09.038

Background: Patient-maintained propofol TCI sedation (PMPS) allows patients to titrate their own target-controlled infusion (TCI) delivery of propofol sedation using a handheld button. The aim of this RCT was to compare PMPS with anaesthetist-control...

Intra-tracheal multiplexed sensing of contact pressure and perfusion (2021)
Journal Article
Correia, R., Gadsby, B., Korposh, S., Norris, A. M., Hayes-Gill, B. R., Sinha, R., Hardman, J. G., Gardner, D. S., Talbot, S., Harvey, D., McGlashan, J., & Morgan, S. P. (2022). Intra-tracheal multiplexed sensing of contact pressure and perfusion. Biomedical Optics Express, 13(1), 48-64. https://doi.org/10.1364/BOE.442165

Incorrect endotracheal tube (ETT) cuff inflation pressure causes significant problems for intubated patients. The technical development and first in vivo use of a smart ETT for measurements at the cuff-trachea interface during mechanical ventilation...

Pre-hospital continuous positive airway pressure after blast lung injury and hypovolaemic shock: a modelling study (2021)
Journal Article
Mistry, S., Das, A., Hardman, J. G., Bates, D. G., & Scott, T. E. (2022). Pre-hospital continuous positive airway pressure after blast lung injury and hypovolaemic shock: a modelling study. British Journal of Anaesthesia, 128(2), e151-e157. https://doi.org/10.1016/j.bja.2021.10.012

Background
In non-traumatic respiratory failure, pre-hospital application of CPAP reduces the need for intubation. Primary blast lung injury (PBLI) accompanied by haemorrhagic shock is common after mass casualty incidents. We hypothesised that pre-h...

High risk of patient self-inflicted lung injury in COVID-19 with frequently encountered spontaneous breathing patterns: a computational modelling study (2021)
Journal Article
Weaver, L., Das, A., Saffaran, S., Yehya, N., Scott, T. E., Chikhani, M., Laffey, J. G., Hardman, J. G., Camporota, L., & Bates, D. G. (2021). High risk of patient self-inflicted lung injury in COVID-19 with frequently encountered spontaneous breathing patterns: a computational modelling study. Annals of Intensive Care, 11(1), Article 109. https://doi.org/10.1186/s13613-021-00904-7

Background: There is ongoing controversy regarding the potential for increased respiratory effort to generate patient self-inflicted lung injury (P-SILI) in spontaneously breathing patients with COVID-19 acute hypoxaemic respiratory failure. However,... Read More about High risk of patient self-inflicted lung injury in COVID-19 with frequently encountered spontaneous breathing patterns: a computational modelling study.

Ventilation strategies for front of neck airway rescue: an in silico study (2021)
Journal Article
Laviola, M., Niklas, C., Das, A., Bates, D. G., & Hardman, J. G. (2021). Ventilation strategies for front of neck airway rescue: an in silico study. British Journal of Anaesthesia, 126(6), 1226-1236. https://doi.org/10.1016/j.bja.2021.01.030

Background. During induction of general anaesthesia a “can’t intubate, can’t oxygenate” (CICO) situation can arise, leading to severe hypoxaemia. Evidence is scarce to guide ventilation strategies for small-bore front of neck airways that ensure effe...

Effect of variable pre-oxygenation endpoints on safe apnoea time using high flow nasal oxygen for women in labour: a modelling investigation (2021)
Journal Article
Stolady, D., Laviola, M., Pillai, A., & Hardman, J. G. (2021). Effect of variable pre-oxygenation endpoints on safe apnoea time using high flow nasal oxygen for women in labour: a modelling investigation. British Journal of Anaesthesia, 126(4), 889-895. https://doi.org/10.1016/j.bja.2020.12.031

Background

Studies of pulmonary denitrogenation (pre-oxygenation) in obstetric populations have shown high flow nasal oxygen therapy (HFNO) is inferior to facemask techniques. HFNO achieves median end-tidal oxygen fraction (FE′O2) of 0.87 after 3...
