“…In the face of this, Forfori et al trivialize the studies of Nguyen et al [3] and Artuso et al [4], which both used TDCO as their test method to determine CO and the derived indices of cardiac index (CI) stroke volume SV, stroke index (SI) and systemic vascular resistance (SVR) and SVRI. Alleging equivalence to TDCO, the authors emphasize that their results for SV are similar to those of Dumont et al [5], which are, on the mean, 64 and 72 mL, respectively.…”

“…In spite of the reported untoward hemodynamic effects attributed to laparoscopy, 18 obese patients tolerate the pneumoperitoneum surprisingly well, without experiencing a fall in cardiac output. 21 Intraoperative analgesia was provided with aliquots of fentanyl. The fentanyl dose was possibly high in some short cases (especially short laparoscopies), resulting in postoperative ventilatory depression and delayed extubation in the PACU (eight vs two cases in laparoscopic vs OPG).…”

Anesthesia for restrictive bariatric surgery (gastric bypass not included): laparoscopic vs open procedures

et al. 2004

Publications regarding anesthetic management for weight reduction surgery are scarce. We reviewed the records of 234 patients who underwent bariatric restrictive procedures (gastric bypass not included) from May 1999 to September 2000. Variables analyzed included demographics, anesthetic data and perioperative course. Patients were allocated into two groups: laparoscopic (LPG) and open procedures (OPG), comprising 167 and 67 patients respectively. Obstructive sleep apnea was present in 4.8% in LPG vs 6.1% in OPG. Awake fiberoptic intubation was performed in 3.6% in LPG and 1.5% in OPG. The other patients were anesthetized with rapid sequence induction (classic or modified). Grade III laryngoscopy was present in 6% in LPG and 7.1% in OPG. No intraoperative complications were encountered. Postoperative PACU follow-up time was similar. In both groups, i.v. meperidine was most frequently used for postoperative analgesia (in the PACU), as compared to the other analgesics employed (Po0.03). Early postoperative complications (prolonged mechanical ventilation, unplanned ICU admission, sepsis, reoperation) occurred more frequently in OPG, but the difference between the two groups was statistically insignificant (Po0.08). The length of hospitalization was 3.871.4 days in LPG and 6.276.6 in OPG (Po0.01). Mortality was zero. Anesthesia for restrictive bariatric surgery (both open and laparoscopic approaches) was associated with few complications. SUMMARY STATEMENT: We reviewed the records of 234 patients who underwent restrictive bariatric procedures (gastric bypass not included) from May 1999 to September 2000, in regard to perioperative complications. Anesthesia was associated with no intraoperative and few postoperative complications.

The present study investigates the relations between obesity and survival during intra-abdominal hypertension (IAH) in diet induced obesity Wistar rats. The animals from model group were fed with high-fat diet for 45 days. Intra-abdominal pressure in both groups (control and model) was elevated by manual system for air insufflations. The pressure was of value (25mmHg) corresponding to the typical values observed in abdominal compartment syndrome. Quantification of the serum levels of serum amyloid A was carried out after deflation. The results interpretation was made in correlation with clinical observations in patients with proved cardiovascular diseases caused by obesity, as well as with patients to whom surgery had caused an increased intra-abdominal pressure. Experimental observations have shown increased survival in diet induced obesity rats with IAH compared to control rats with IAH. Increased resistance to IAH is due to changes in the structure and in the mechanical characteristics of the abdominal wall, following obesity.

Hemodynamic Changes During Laparoscopic Gastroplasty in Morbidly Obese Patients

Abstract: When compared to nonobese patients our obese patients tolerated the pneumoperitoneum surprisingly well, without experiencing fall in cardiac output. The hemodynamic consequences of peritoneal insufflation seem to be different in obese and nonobese patients.
