مستخلص: Objective: The accuracy of tunneled external ventricular drain (EVD) placement has been shown to be similar among practitioners of varying experience, but this has not yet been investigated for bolt EVDs. Tunneled and bolt EVDs are distinct techniques, and it is unclear if conclusions regarding accuracy can be inferred from one method to the other. The goal of this study was to determine whether neurosurgical experience influences the accuracy of bolt EVD placement. Methods: We performed a single-center retrospective analysis of accuracy of bolt EVD placement between 1st December 2018 and 31st May 2020, comparing the accuracy outcomes between three levels of training (junior trainees (JT); mid-grade trainees (MT); senior trainees/fellows (ST)). Accuracy was determined radiologically by two methods: Kakarla grade and by measuring the distance of the catheter tip to its optimal position (DTOP) at the foramen of Monro. Results: Eighty-seven patients underwent insertion of bolt EVDs, of which n = 19 by JT, n = 40 by MT and n = 28 by ST, with a significant difference found between training grades in the median Kakarla grade (p = 0.0055) and in the accuracy of placement as per DTOP (p = 0.0168). Conclusions: In contrast to previous published results on tunneled EVDs, we demonstrate that the accuracy of bolt EVD placement is dependent on neurosurgical experience. Our results draw awareness to the fact that the bolt EVD technique can represent a challenge for less experienced practitioners and underline the importance of dedicated training to support the safe insertion of bolt ventricular catheters.

مستخلص: Introduction. The Modelled Anatomical Replica for Training Young Neurosurgeons (MARTYN) is a novel simulation model developed by the Royal College of Surgeons England (RCSEng). This study describes the development of the model and aims to determine its feasibility as a potential future training tool. Methods and materials. Traditional model-making methods were used to develop a prototype. Initial procedural trials tested the feasibility of the model. Eighteen participants, grouped by experience (nine novices, four intermediates and five experienced), completed two tasks: a craniotomy and a burr hole followed by insertion of an external ventricular drain (EVD). Subjective data on confidence, usefulness, realism and preference to other training modalities were collected via a standardised questionnaire and a 5-point Likert scale. Results. Preliminary trials of the model prototype demonstrated feasibility. The novice group had the greatest self-reported benefit from MARTYN training, with significant increases in self-rated confidence in both the craniotomy ( p < 0.01) and EVD insertion ( p < 0.05) procedures. MARTYN was reported to having good visual and tactile realism overall with the bone component being considered highly realistic. The model was reported to be a useful training tool. When asked to rank preferred training modalities, operative experience was chosen first with cadaveric training and MARTYN consistently scoring a second choice. Conclusions. MARTYN was developed with the intention to fill the current niche for an inexpensive synthetic model head. This study shows that the use of MARTYN for training is both feasible and realistic. We demonstrate a preliminary face and construct validity of the model in this pilot study. With the reduction in working hours, we believe this model will be a suitable supplement to the current ST 1-3 level cadaveric training and will have a positive impact on patient safety.

مستخلص: The article focuses on the development of use of MARTYN, or Modelled Anatomical Replica for Training Young Neurosurgeons, cranial model at the Royal College of Surgeons (RCS) of England as a formal training tool for neurosurgeons. An overview of the pilot craniotomy with external ventricular drain insertion performed in the operating theatre at the RCS simulation suite is provided. Also noted is the patient safety dilemma facing training junior neurosurgeons regarding the use of MARTYN.
