Monitoring is the global method of observation and data recording in relation to body organ and system function that afford constant information to ensure continuous evalutation of the patient's physical condition. Basic monitoring provides essential information for assessing the vital signs, both circulatory and respiratory, and fundamentally comprises the control of blood pressure (BP) and heart rate (HR) and rhythm. Pulse oxymetry is used to record HR and oxygen saturation. The objective of the study was to assess and compare hemodynamic changes by monitoring oxygen saturation level changes during periodontal surgical and nonsurgical therapy.
A cross-sectional observational study was conducted in 30 chronic periodontitis patients. Patients were divided into two groups; Group A consisted of 15 patients undergoing surgical periodontal therapy, Group B consisted of 15 patients undergoing nonsurgical periodontal therapy. The hemodynamic changes were evaluated by monitoring HR and oxygen saturation level using pulse oxymeter (SaO₂). HR and SaO₂ were monitored continuously and registered pre-operatively, i.e. 10 minutes before the procedure, intra-operatively and postoperatively, i.e. 10 minutes after the procedure. One-way analysis of variance test (ANOVA) was performed for data analysis.
Both the groups showed a slight fall in oxygen saturation levels intraoperatively, but within the normal range. More decrease in oxygen saturation levels was observed in nonsurgical periodontal therapy as compared to surgical periodontal therapy at intraoperative levels. The differences in the values were statistically significant. There was no statistical difference seen in the postoperative and preoperative values.
Most of the hemodynamic changes induced during the periodontal therapy were within normal limits, taking into consideration the anxiety and stress produced by the surgical intervention. The hemodynamic change was more in nonsurgical as compared to surgical periodontal therapy.
监测是针对身体器官和系统功能进行观察及数据记录的全面方法，能提供持续信息以确保对患者身体状况进行持续评估。基本监测为评估循环和呼吸等生命体征提供重要信息，主要包括血压（BP）、心率（HR）及心律的监测。脉搏血氧饱和度测定用于记录心率和血氧饱和度。本研究的目的是通过监测牙周手术和非手术治疗期间血氧饱和度水平的变化来评估和比较血流动力学变化。
对30例慢性牙周炎患者进行了横断面观察性研究。患者分为两组；A组由15例行牙周手术治疗的患者组成，B组由15例行非手术牙周治疗的患者组成。使用脉搏血氧仪（SaO₂）监测心率和血氧饱和度水平来评估血流动力学变化。术前即手术前10分钟、术中及术后即手术后10分钟持续监测心率和血氧饱和度并记录。采用单因素方差分析进行数据分析。
两组在术中血氧饱和度水平均有轻微下降，但在正常范围内。与牙周手术治疗相比，非手术牙周治疗在术中的血氧饱和度水平下降更多。这些数值差异具有统计学意义。术后与术前数值无统计学差异。
考虑到手术干预产生的焦虑和压力，牙周治疗期间引起的大多数血流动力学变化在正常范围内。与牙周手术治疗相比，非手术治疗时血流动力学变化更大。
