Limitations of clinical application of closed-loop feedback analgesia system

The last article mainly explained the closed-loop feedback labor analgesia system in labor analgesia. This article mainly talks about its limitations.

The closed-loop feedback analgesic pump has certain advantages over the traditional self-controlled analgesia pump. It is a major technological advancement in labor analgesia in recent years. The automatic and individualized drug delivery model has broad development prospects.

Closed-loop feedback labor analgesia advocates using a small amount of drugs to maintain the analgesic effect during the incubation period. As the contractions increase and the demand for maternal analgesia increases, the use of drugs is gradually increased, which not only improves the maternal delivery experience but also eases the workload of the doctor.

But this technology also obviously has certain shortcomings, as follows:

1. The principle of closed-loop feedback technology is more complicated than traditional self-control analgesic pumps, which may cause patients to be incomprehensible and resist emotions and affect the effect of use.

2. The technology also requires good human-computer interaction, and the parturient must have a certain degree of compliance. Once there is pain, press the PCA in time, and press repeatedly when the pain becomes worse, so that the pain information can be effectively feedback. In the actual operation process, many parturients forget to press because of severe pain, causing the machine to receive "negative feedback" information, reducing or stopping the administration, which affects the analgesic effect.

At present, closed-loop feedback labor analgesia technology is only used in scientific research, and a large number of clinical studies are still needed to prove its effectiveness and safety, as well as the setting of ideal parameters. 

This also requires anesthesiologists, obstetricians and midwives to work together to develop optimization An analgesic program to help women give birth safely and comfortably.
