Description
본 발명은 목표 농도 주입의 복구 조절 방법에 관한 것으로서, 더 상세하게는 TCI(target controlled infusion pump) 시스템의 사용 중 갑작스러운 장비 오류상황 발생시, 이전 주입정보 및 주입 진행이력 즉, TCI시스템 상태정보를 기초로, 장비 오류상황 발생 이후 감소된 농도를 계산하여 목표 농도까지 복구하도록 자동 세팅한 상태에서 연결 주입이 가능하도록 구성함으로써, 안정적으로 약동학적 및 약역학적 특성을 유지할 수 있을 뿐만 아니라, 안정적인 마취 및 진정 레벨 조절이 가능한 목표 농도 주입의 복구 조절 방법에 관한 것이다.The present invention relates to a recovery control method of target concentration injection, and more particularly, when a sudden equipment error situation occurs during use of a target controlled infusion pump (TCI) system, previous injection information and injection progress history, that is, TCI system state information Based on the basis, it is possible to maintain stable pharmacokinetic and pharmacodynamic properties, as well as stable anesthesia and It relates to a method for controlling restoration of a target concentration infusion in which sedation level control is possible.
일반적으로 환자의 마취 및 진정을 목적으로 수술 전후 일회적으로 마취 및 진정제를 투여하게 되는데, 반감기가 짧고 체내 축적이 잘 일어나지 않는 정맥 마취제가 많이 사용되고 있다. 최근 들어, 지속 주입 방법에 대한 사용자의 이해도가 높아짐에 따라 목표농도조절 주입기(target controlled infusion pump, 이하 TCI)를 이용하여 환자의 마취 및 진정이 시행되고 있으며, 이러한 TCI가 공개특허 제10-2001-0079309호(이하, '특허문헌 1'이라 함.)에 개시되어 있다.In general, for the purpose of anesthesia and sedation of a patient, anesthesia and sedatives are administered once before and after surgery, and intravenous anesthetics have a short half-life and do not easily accumulate in the body. Recently, as the user's understanding of the continuous infusion method increases, anesthesia and sedation of the patient are being performed using a target controlled infusion pump (hereinafter referred to as TCI), and such TCI is disclosed in Patent Publication No. 10-2001 -0079309 (hereinafter referred to as 'Patent Document 1') is disclosed.
상기 특허문헌 1은 TCI를 통해 마취 및 진정을 유도할 때 성별, 연령 및 신체 상태(키,몸무게) 등을 고려하여 약제의 혈중 목표 농도(plasma site)와 효과처 목표 농도(effect site)를 설정하여 마취 및 진정을 유도하게 되며, 따라서 혈중 농도와 효과처 농도 변화가 적고 안정된 약동학적 및 약역학적 특성을 갖는 것이 특징이다.The Patent Document 1 sets a target concentration in the blood and an effect site of a drug in consideration of gender, age, and physical condition (height, weight) when inducing anesthesia and sedation through TCI. Thus, it induces anesthesia and sedation, so it is characterized by small changes in blood concentration and effect concentration and stable pharmacokinetic and pharmacodynamic properties.
또한, 마취 약제나 기타 약제의 정맥 주입 시, 사용상의 편리성과 사용 후 임상적 부작용이 거의 없어 경험이 부족한 마취의들도 간단한 조작으로 마취 깊이를 신속하고 자동적으로 조절할 수 있도록 하여 마취의가 수술 중 마취깊이 조절에 투입된 시간을 환자 감시에 좀더 많은 시간을 할애할 수 있게 된다.In addition, when injecting anesthetic drugs or other drugs intravenously, it is convenient to use and has few clinical side effects. More time spent on controlling the depth of anesthesia can be devoted to monitoring the patient.
그러나, 약동학적 및 약역학적 특성은 통계적인 것으로 사람마다 약물에 대한 반응은 다를 수 있으며 특히 진정을 유지하는 과정에서 환자의 호흡 억제 및 불충분한 진정 깊이 등의 임상 증상과 환자의 반응을 보면서 목표 농도를 조절해야 한다는 문제점이 있었다.However, pharmacokinetic and pharmacodynamic characteristics are statistical, and the response to drugs may vary from person to person. In particular, in the process of maintaining sedation, the target concentration while observing the patient's response and clinical symptoms such as respiratory depression and insufficient depth of sedation. There was a problem that had to be adjusted.

It is configured to maintain the sedation level of
그러나, TCI 시스템 사용 중 배터리 방전 등 갑작스러운 전원 셧다운(shutdown)이 발생하는 경우, 전원을 복구하여 TCI 시스템을 새롭게 세팅 후 사용하도록 구성되는데, 이로 인하여, 도 1에 도시된 바와 같이, 셧다운(shutdown) 기간 동안 환자의 체내 변화된 농도를 반영하지 못하고 처음부터 새롭게 목표 농도를 주입하게 되는 상황이 발생함에 따라, 실제로 환자의 체내 농도가 높아지거나, 계산 농도와 체내 농도의 오차가 더욱 커지게 되는 문제점이 있었다. However, when a sudden power shutdown such as battery discharge occurs while the TCI system is in use, the power is restored and the TCI system is newly set and used. As a result, as shown in FIG. 1 , the shutdown (shutdown) occurs. ), as a situation arises that the target concentration is newly injected from the beginning without reflecting the changed concentration in the patient's body during the period, the actual concentration in the patient's body increases, or the error between the calculated concentration and the concentration in the body becomes larger. there was.

Hereinafter, power shutdown will be described as an example.
본 발명은 TCI(target controlled infusion pump) 시스템을 통해 마취진정제를 투여하는 과정에서 전원 셧다운(shutdown)이 발생하는 경우, 셧다운(shutdown) 기간(Tshutdown) 동안 환자의 체내 변화된 농도를 반영하여 목표 농도를 연결 주입하도록 구성되는데, 이를 위하여, TCI(target controlled infusion pump) 시스템의 사용 중, 셧다운(shutdown) 상황 발생(S150)을 대비하여 환자정보, TCI 주입정보를 포함하는 셧다운(shutdown) 상태정보를 저장(S100)하도록 구성된다. 이때, 셧다운(shutdown) 상태정보에는 parameter 정보, 시각정보, 주입 진행 이력 등이 포함되는 것이 바람직하다.In the present invention, when a power shutdown occurs in the process of administering an anesthetic sedative through a target controlled infusion pump (TCI) system, the target concentration is set by reflecting the changed concentration in the patient's body during the shutdown period (Tshutdown). It is configured to connect and inject, for this purpose, in use of a target controlled infusion pump (TCI) system, in preparation for a shutdown situation (S150), shutdown state information including patient information and TCI infusion information is stored It is configured to (S100). In this case, the shutdown state information preferably includes parameter information, time information, injection progress history, and the like.
상기 셧다운(shutdown) 상태정보는 복구 과정에서 환자의 정확한 상태를 파악하여 목표 농도를 연결 주입하는 것이 가능하도록 1초 간격으로 항시 저장되는 것이 좋다.It is preferable that the shutdown state information is always stored at intervals of 1 second so that it is possible to connect and inject the target concentration by grasping the exact state of the patient in the recovery process.
