BACKGROUND: Childbirth can have a substantial impact on maternal health-related quality of life. Cesarean delivery is the most performed inpatient operation, yet little is known about normal postpartum recovery profiles. The primary aim of our study was to longitudinally evaluate global health visual analog scale (GHVAS; 0–100) scores up to 12 weeks after scheduled cesarean delivery and identify the time to plateau of scores. The secondary aims were to evaluate different domains of postpartum recovery using validated patient-reported outcome measures (Obstetric Quality of Recovery score [ObsQoR-10] and 5-level 5-dimensional EuroQol questionnaire [EQ-5D]). METHODS: After institutional review board approval, this single-center, prospective longitudinal study enrolled healthy women scheduled for cesarean delivery. Women were excluded for gestational age <32 weeks, neonatal demise, neonatal intensive care unit admission, inability to read or understand English, and if general anesthesia was used. Women completed baseline surveys before delivery and then at 24 and 48 hours after delivery. After hospital discharge, women completed surveys (including GHVAS, OBsQoR-10, EQ-5D, Edinburgh Postnatal Depression Scale, and activities of daily living) at 1 week, 3 weeks, 6 weeks, and 12 weeks postpartum. One-way repeated measures analysis of variance (ANOVA) was used to detect the difference in GHVAS and postpartum recovery outcomes with different follow-up time points. RESULTS: We enrolled 66 parturients and 3 were withdrawn. Response rates were 95%, 84%, 83%, and 76% at 1, 3, 6, and 12 weeks, respectively. Mean ± standard deviation [SD] GHVAS scores were 78 ± 16 at baseline, 64 ± 17 at 24 hours, 69 ± 15 at 48 hours, 75 ± 19 at 1 week, 88 ± 11 at 3 weeks, 88 ± 15 at 6 weeks, and 90 ± 12 at 12 weeks postpartum ( P < .001). The global health VAS improved up until week 3 and then plateaued close to the maximum score between 3 weeks and 12 weeks postpartum. Mean ± SD ObsQoR-10 scores were 75 ± 15 at 24 hours, 85 ± 10 at 48 hours, and 81 ± 28 at 1 week postpartum ( P = .003). The mean ± SD EQ-5D composite scores improved at 6 weeks (4.9 ± 2.9) and 3 months (4.2 ± 2.6) compared to baseline (6.5 ± 1.8) with usual activities ( P = .001) and pain/discomfort ( P < .001) showing significant improvement over time. ObsQoR-10 score at 24 hours correlated with ObsQoR-10 scores at 48 hours (r = 0.629, P < .001) and 1 week (r = 0.429, P < .001) but did not correlate with EQ-5D scores at 6 weeks and 12 weeks. CONCLUSIONS: Our study demonstrates that GHVAS after scheduled CD plateaus at week 3. This data can be used to inform patients about the anticipated trajectory of key postpartum recovery domains up to 12 weeks postpartum.
Quantitative assessment of painful diabetic peripheral neuropathy after high-frequency spinal cord stimulation: a pilot study
Abstract Objective Randomized trials have demonstrated efficacy of spinal cord stimulation (SCS) for treatment of painful diabetic neuropathy (PDN). Preliminary data suggested that treatment of PDN with high-frequency SCS resulted in improvements on neurological examination. The purpose of the present study was to explore whether patients with PDN treated with high-frequency SCS would have improvements in lower-extremity peripheral nerve function. Design Prospective cohort study in an outpatient clinical practice at a tertiary care center. Methods Patients with PDN were treated with high-frequency SCS and followed up for 12 months after SCS implantation with clinical outcomes assessments of pain intensity, neuropathic symptoms, and neurological function. Small-fiber sudomotor function was assessed with the quantitative sudomotor axon reflex test (QSART), and large-fiber function was assessed with nerve conduction studies (NCS). Lower-extremity perfusion was assessed with laser Doppler flowmetry. Results Nine patients completed 12-month follow-up visits and were observed to have improvements in lower-extremity pain, weakness, and positive sensory symptoms. Neuropathy impairment scores were improved, and 2 patients had recovery of sensory responses on NCS. A reduction in sweat volume on QSART was observed in the proximal leg but not at other sites. No significant differences were noted in lower-extremity perfusion or NCS as compared with baseline. Conclusions The improvement in pain relief was concordant with improvement in neuropathy symptoms. The findings from this study provide encouraging preliminary data in support of the hypothesis of a positive effect of SCS on peripheral neuropathy, but the findings are based on small numbers and require further evaluation.

Noninvasive Cardiac Output Monitoring (NICOM) in the Critically Ill Patient Undergoing Endotracheal Intubation: A Prospective Observational Study
Background: Cardiovascular instability occurring during endotracheal intubation (ETI) in the critically ill is a commonly recognized phenomenon. However, this complication has not been evaluated in terms of the physiological cause (ie, decreased preload, contractility, or afterload) leading to the instability. Thus, the aim of the current investigation was to describe the hemodynamics occurring during ETI with noninvasive physiologic monitoring and to collect preliminary data on the hemodynamic effects of induction agents and positive pressure ventilation. Methods: A multicenter prospective study enrolling adult (≥18 years) critically ill patients undergoing ETI with noninvasive cardiac output monitoring in a medical/surgical intensive care unit from June 2018 to May 2019 was conducted. This study used the Cheetah Medical noninvasive cardiac output monitor to collect hemodynamic data during the peri-intubation period. Additional data collected included baseline characteristics such as illness severity, peri-intubation pharmacologic administration, and mechanical ventilation settings. Results: From the original 27 patients, only 19 (70%) patients had complete data and were included in the final analysis. Propofol was the most common sedative 8 (42%) followed by ketamine 6 (32%) and etomidate 5 (26%). Patients given propofol demonstrated a decrease in total peripheral resistance index (delta change [dynes × s/cm −5 /m 2 ]: −2.7 ± 778.2) but stabilization in cardiac index (delta change (L/min/m 2 ]: 0.1 ± 1.5) while etomidate and ketamine demonstrated increases in total peripheral resistance index (etomidate delta change [dynes × s/cm −5 /m 2 ]: 302.1 ± 414.3; ketamine delta change [dynes × s/cm −5 /m 2 ]: 278.7 ± 418.9) but only etomidate resulted in a decrease in cardiac index (delta change [L/min/m 2 ]: −0.3 ± 0.5). Positive pressure ventilation resulted in minimal changes to hemodynamics during ETI. Conclusions: The current study demonstrates that although propofol administration leads to a decrease in total peripheral resistance index, cardiac index is maintained while etomidate leads to a decrease in cardiac index with both etomidate and ketamine increasing total peripheral resistance index. These hemodynamic profiles are minimally affected by positive pressure ventilation. Study registration: ClinicalTrials.gov ID, NCT03525743.
