Abstract
Purpose
The objective of this study was to describe some components of the perioperative practice in liver transplantation as reported by clinicians.
Methods
We conducted a cross-sectional clinical practice survey using an online instrument containing questions on selected themes related to the perioperative care of liver transplant recipients. We sent email invitations to Canadian anesthesiologists, Canadian surgeons, and French anesthesiologists specialized in liver transplantation. We used five-point Likert-type scales (from “never” to “always”) and numerical or categorical answers. Results are presented as medians or proportions.
Results
We obtained answers from 130 participants (estimated response rate of 71% in Canada and 26% in France). Respondents reported rarely using transesophageal echocardiography routinely but often using it for hemodynamic instability, often using an intraoperative goal-directed hemodynamic management strategy, and never using a phlebotomy (medians from ordinal scales). Fifty-nine percent of respondents reported using a restrictive fluid management strategy to manage hemodynamic instability during the dissection phase. Forty-two percent and 15% of respondents reported using viscoelastic tests to guide intraoperative and postoperative transfusions, respectively. Fifty-four percent of respondents reported not pre-emptively treating preoperative coagulations disturbances, and 91% reported treating them intraoperatively only when bleeding was significant. Most respondents (48–64%) did not have an opinion on the maximal graft ischemic times. Forty-seven percent of respondents reported that a piggyback technique was the preferred vena cava anastomosis approach.
Conclusion
Different interventions were reported to be used regarding most components of perioperative care in liver transplantation. Our results suggest that significant equipoise exists on the optimal perioperative management of this population.
Résumé
Objectif
L’objectif de cette étude était de décrire certaines composantes de la pratique périopératoire en transplantation hépatique telles que rapportées par les cliniciens.
Méthode
Nous avons mené un sondage transversal sur la pratique clinique à l’aide d’un instrument en ligne comportant des questions sur des thèmes sélectionnés liés aux soins périopératoires des receveurs de greffe du foie. Nous avons envoyé des invitations par courriel à des anesthésiologistes canadiens, des chirurgiens canadiens et des anesthésiologistes français spécialisés en transplantation hépatique. Nous avons utilisé des échelles de type Likert à cinq points (de « jamais » à « toujours ») et des réponses numériques ou catégorielles. Les résultats sont présentés sous forme de médianes ou de proportions.
Résultats
Nous avons obtenu des réponses de 130 participants (taux de réponse estimé à 71 % au Canada et à 26 % en France). Les répondants ont déclaré utiliser rarement l’échocardiographie transœsophagienne de routine, mais l’utiliser fréquemment pour l’instabilité hémodynamique, souvent en utilisant une stratégie de prise en charge hémodynamique peropératoire axée sur les objectifs, et jamais en utilisant une phlébotomie (médianes des échelles ordinales). Cinquante-neuf pour cent des répondants ont déclaré utiliser une stratégie restrictive de gestion liquidienne pour prendre en charge l’instabilité hémodynamique pendant la phase de dissection. Quarante-deux pour cent et 15 % des répondants ont déclaré utiliser des tests viscoélastiques pour guider les transfusions peropératoires et postopératoires, respectivement. Cinquante-quatre pour cent des répondants ont déclaré ne pas traiter préventivement les troubles préopératoires de la coagulation, et 91 % ont déclaré les traiter en peropératoire uniquement lorsque les saignements étaient importants. La plupart des répondants (48-64 %) n’avaient pas d’opinion sur les temps ischémiques maximaux du greffon. Quarante-sept pour cent des répondants ont déclaré qu’une technique de ‘piggyback’ (anastomose latéroterminale) était l’approche préférée pour l’anastomose de la veine cave.
Conclusion
Différentes interventions ont été signalées pour la plupart des composantes des soins périopératoires dans la transplantation hépatique. Nos résultats suggèrent qu’il existe une incertitude significative concernant la prise en charge périopératoire optimale de cette population.
