“…The shape of brain wave shows the spontaneous and rhythmic electrical activity of brain cell group, which is generally described by the characteristics of amplitude, frequency, and phase. During general anesthesia, EEG frequency changes sequentially with the deepening or shallowing of anesthesia and has a functional relationship with anesthetic concentration, so it can be used to reflect the depth of anesthesia [ 11 ]. However, in the early stage, the time-domain characteristics of EEG were mostly used to reflect the depth of anesthesia, mainly analyzing the geometric properties of EEG waveform.…”

Laparoscopic surgery has the advantages of less trauma and quick recovery, and it is more and more favored by surgeons and patients in clinical practice. However, the impact of carbon dioxide pneumoperitoneum on the body during laparoscopic surgery has attracted the attention of many scholars. Pneumoperitoneum can cause increased cerebral blood flow and increased intracranial pressure, cerebral metabolic rate is highly correlated with blood carbon dioxide partial pressure, and cerebral metabolism without cardiopulmonary bypass is linearly correlated with the depth of anesthesia. Electroencephalographic (EEG) bispectral index (BIS) is a signal analysis method, which can directly measure the effect of drugs on the cerebral cortex and reflect the depth of anesthesia. Based on this, this study takes smart medical treatment as the background and uses the improved BP neural network as a tool to explore the effect of carbon dioxide on EEG bispectral index under intravenous target-controlled anesthesia. The main purpose is to observe the correlation between arterial blood carbon dioxide partial pressure and EEG bispectral index under propofol target-controlled anesthesia during retroperitoneal laparoscopic surgery. The experimental results show that the model proposed in this study can efficiently and accurately obtain the size of the influencing factors, which provides a clinical basis for the anesthesia management and anesthesia depth regulation of carbon dioxide pneumoperitoneum laparoscopic surgery.

“…Avci S et al predicted an average BIS score of 70.8 for predicting the associated complications. 12 We observed only a few untoward events at a BIS range of 76-94, none requiring any intervention. The included patients belonged to the non-geriatric age group and had no systemic comorbidities.…”

“…These results are in coherence with previous trial conducted to evaluate the compliance between the BIS and RSS under the different settings. 12 The effect of baseline characteristics, especially age on the BIS values for a particular depth of sedation, has not been well addressed. Katoh et al showed that BIS at which response to verbal commands was suppressed is not affected by the age of the patient.…”

Background: Bispectral index (BIS) has been in practice as an objective tool to measure the depth of conscious sedation. The data on adequate levels for awake fiberoptic nasotracheal intubation (AFNI) is however scarce. We aimed to obtain an optimal level of BIS required for achieving the adequate conscious sedation in AFNI procedure. Methods: In a prospective, observational, outcome assessor blinded cohort trial, 94 consecutive patients with anticipated difficult intubation and undergoing AFNI for any elective surgery were enrolled. The topical anesthesia and sedation were induced with lidocaine and dexmedetomidine, while keeping the patient awake. The sedation levels were targeted to BIS ≤90 and Ramsay sedation score (RSS)≥2 to attempt intubation. Propofol bolus were administered if patients get agitated. The primary outcome was "Stable BIS", the lowest BIS at which intubation could be feasibly performed. A receiver operator characteristic curve, Youden index, and correlation analysis were used. Results: The optimal criterion for BIS was obtained as ≤86 (AUC: 0.80, sensitivity 88.30%, specificity 61.45%, Youden index 49.74). The stable BIS ranged from 80 to 88, while RSS varied from 1 to 3. The BIS and RSS correlated significantly (r: 0.83). The stable BIS was independent of any baseline characteristics. Six patients had transient untoward events, none requiring any intervention. Conclusion: BIS serves as an effective objective tool for titrating the depth of conscious sedation. We advocate a BIS range of 80-86 for feasibly performing the AFNI procedure.

“…Local anesthesia employed in such way decreases the painful stimulus during the procedure and simplifies the medical anesthesia, aiming to keep the patient at a sedation level commensurate with a level 3 on the Ramsay scale, which has been reported to achieve better anxiolysis and intra-and postoperative analgesia. 39…”

Background: To demonstrate the feasibility of an endoscopically assisted minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) and to study clinical outcomes with the use of a static oblique bulletshaped cannulated poly-ether-ether-ketone (PEEK) lumbar interbody fusion cage in conjunction with platelet enriched plasma infused allograft cancellous chips and posterior supplemental fixation.Methods: In this retrospective study of 43 patients who underwent endoscopically assisted MIS-TLIF for spondylolisthesis (53.5%) and stenosis (46.3%), the Oswestry Disability Index, the visual analog scale (VAS) for back and leg pain, and the modified Macnab criteria were used as primary clinical outcome measures. Clinical outcomes were cross-tabulated against fusion grade using the Bridwell classification of interbody fusion.Results: The majority of patients (90.7%) had excellent (8/43; 18.6%) and good (31/43; 72.1%) Macnab outcomes. There were significant VAS back score reductions from an average preoperative values of 8.9070 to a postoperative VAS score of 3.8605, and a score of 2.7674 at final follow-up (P , .0001). The reductions in the VAS leg scores were also significant from preoperative score of 5.58 to a postoperative value of 2.16, and a final follow-up score of 1.67 (P , .0001); the Oswestry Disability Index score went from a preoperative value of 54.4 to 23.3 postoperatively and 18.5 at the final follow-up ( P , .0001). The vast majority of patients (92.9%) with Bridwell grade I fusion had excellent and good Macnab outcomes (P ¼ .027).Conclusions: The authors recommend the use of an endoscope as an adjunct to MIS-TLIF, a minimally invasive spinal surgery technique in which many surgeons may be well versed and have a great deal of experience. Clinical outcomes with the endoscopic interbody fusion procedure with a static PEEK cage in conjunction with platelet-enriched bone allograft were favorable.
